Game Collision

I am trying to republish an already existing Survey123 in ArcGIS Enterprise. All I did was add a new field to the survey called "survey_version" and when I try to republish it, I get the following error message: ERROR: Field name collision found: survey_version." Error code: 500.
Is there another field named 'survey_version' (possibly different capitalization) in the feature service? The error message is indicating that it cannot add the field as there is already one with that name.
That's what I was thinking. But there are no fields named 'survey_version'. I checked both the excel document and the hosted feature service and no fields exist with that name. Furthermore, when I click the Publish button in Survey123, it gives me a warning that the survey has already been published and that one field was not found in the feature service, which is 'survey_version'. So it definitely appears that it does not previously exist. I'm assuming the solution would be to just create a new Survey123 form. But I was hoping to avoid going that far to fix the problem.
Just to update, I checked the underlying PostgreSQL database of the hosted feature service and the base table contains the 'survey_version' field, but the view does not contain it. I'm just going to publish a brand new Survey123 form.
In physics, a collision is any event in which two or more bodies exert forces on each other in a relatively short time. Although the most common use of the word collision refers to incidents in which two or more objects collide with great force, the scientific use of the term implies nothing about the magnitude of the force.[1]
Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity). The magnitude of the velocity difference just before impact is called the closing speed. All collisions conserve momentum. What distinguishes different types of collisions is whether they also conserve kinetic energy of the system before and after the collision. Collisions are of three types:
The degree to which a collision is elastic or inelastic is quantified by the coefficient of restitution, a value that generally ranges between zero and one. A perfectly elastic collision has a coefficient of restitution of one; a perfectly inelastic collision has a coefficient of restitution of zero. The line of impact is the line that is collinear to the common normal of the surfaces that are closest or in contact during impact. This is the line along which internal force of collision acts during impact, and Newton's coefficient of restitution is defined only along this line.
Collisions in ideal gases approach perfectly elastic collisions, as do scattering interactions of sub-atomic particles which are deflected by the electromagnetic force. Some large-scale interactions like the slingshot type gravitational interactions between satellites and planets are almost perfectly elastic.
The reduction of total kinetic energy is equal to the total kinetic energy before the collision in a center of momentum frame with respect to the system of two particles, because in such a frame the kinetic energy after the collision is zero. In this frame most of the kinetic energy before the collision is that of the particle with the smaller mass. In another frame, in addition to the reduction of kinetic energy there may be a transfer of kinetic energy from one particle to the other; the fact that this depends on the frame shows how relative this is.With time reversed we have the situation of two objects pushed away from each other, e.g. shooting a projectile, or a rocket applying thrust (compare the derivation of the Tsiolkovsky rocket equation).
Collisions of an animal's foot or paw with the underlying substrate are generally termed ground reaction forces. These collisions are inelastic, as kinetic energy is not conserved. An important research topic in prosthetics is quantifying the forces generated during the foot-ground collisions associated with both disabled and non-disabled gait. This quantification typically requires subjects to walk across a force platform (sometimes called a "force plate") as well as detailed kinematic and dynamic (sometimes termed kinetic) analysis.
Hypervelocity is very high velocity, approximately over 3,000 meters per second (11,000 km/h, 6,700 mph, 10,000 ft/s, or Mach 8.8). In particular, hypervelocity is velocity so high that the strength of materials upon impact is very small compared to inertial stresses.[3] Thus, metals and fluids behave alike under hypervelocity impact. An impact under extreme hypervelocity results in vaporization of the impactor and target. For structural metals, hypervelocity is generally considered to be over 2,500 m/s (5,600 mph, 9,000 km/h, 8,200 ft/s, or Mach 7.3). Meteorite craters are also examples of hypervelocity impacts.
The Washington State Patrol Requests for Electronic Collision Records (WRECR) system will allow you to search for a collision report from a computer station with internet access and an e-mail account.
Please note, individuals who are entitled parties will receive a non-redacted copy of the record per the RCW listed below. Additionally, those individuals or agencies that do not meet the definition of entitled parties will be provided a redacted copy of the collision report per RCW 42.56 Public Records Act.
A Collision Records representative is available to assist you with any questions concerning the entry or completion of the Police Traffic Collision Report (PTCR). PTCR forms are available on request by contacting our Section. For instructions on completing a PTCR (Police Traffic Collision Report) please refer to the PTCR Manual.
To order booklets of PTCR (Police Traffic Collision Report) Part A, Part B, Supplemental, or MVR (Civilian Report form) complete the request form and email it as an attachment to collisio...@wsp.wa.gov.
Our office does not accept cash for the purchase of a collision report either by mail or at our office using the kiosk. Our Section only accepts check or money order through the mail, and credit card through our kiosk.
How do I get a copy of my collision report?
Use the WRECR application above to order and download your collision report electronically, or you can request a report by mail using the process above.
Can I go to your office and get my report?
Yes, there is a kiosk located in our lobby to search and order your collision report. Collision Records staff can assist you if needed. Please refer to office hours and contact information to ensure we are open and available.
How long does it take for my report to be available?
Officers completing the collision reports have 2-4 weeks to complete their investigation and have their report approved by their supervisor. It is typically available much sooner, but that is the guideline.
I have a collision on my record, can you remove it?
No, The Department of Licensing (DOL) is the custodian of your Abstract Driving Record (ADR). If there is a mistake on your driving record, please contact DOL at 360-902-3900.
It has been weeks since my collision, I received a no record found on your WRECR application, how come?
If an officer arrived at the scene and completed a report, they typically would provide you an exchange of information or direct you to our website, if the damage threshold of $1,000 was not met based on their observation, they would direct you to complete a citizen report. If unsure, please contact the officer or department that arrived at the scene for verification.

I've looked through most of the available documentation I can find here including the Radio Frequency Interference Troubleshooting Guide ( -Frequency-Interference-Troubleshooting?t=1545053626774). But am still perplexed by what I am seeing in some of our environments. I have policies set up that use the recommendations in the aforementioned guide, but I still see high collision issues across the enterprise.
I'm looking at a 250 in an elementary building right now. Summary State=High Collision. This AP was alerting earlier today and the teacher reported poor performance with a cart of Chromebooks. As this is a new building I had not made any adjustments yet, but in this area I applied radio policies to three APs in close proximity that have rectified similar issues in other buildings.
I also noted that one AP was definitely a bit too loud on 2.4 so I turned down the power. Now, looking at acsp neighbors the loudest I see is -67 on channel 6 on an AP two rooms away with that radio cranked down to 4. Nothing on 5ghz worse than -75.
It was a few year ago, so I am vague on details. It involved the clients showing the wrong MAC address of the default gateway. Verification was done using Wireshark packet capture. It was easy to spot because the clients never received a ARP replies and in the packet details it clearly had the wrong MAC address of the router listed. Proxy ARP is never needed on properly routed network. It is legacy and was originally intended for misconfigured networks.
When it comes to CPU efficiency I could not tell a difference between 6.x, 8.x or 10.x. What I did observe is a high number of DFS events on 6.x, while 8.4 and 10.x would cause APs to stop moving any traffic on the wired interface. Even the serial console port is rendered unavailable. This applies to both AP230s and AP250s
