Here are two screenshots of Union Admin Room Attributes
In the first, number of Observers is shown as 5, and there are 5 listed in the Observers box.
So far, so good.

In the second, number of Observers is also 5 ... but there are none listed.
Why is that?

NOTE: in edit mode, these images are too small to read anything ... but the red circles both have a "5" in them,
and at least you can see that in the first instance there are 5 names listed in the Observers box,
and in the second there are none (I added the red ?).
This won't matter too much after the end of this year when Adobe and all the browsers stop supporting Flash -
good luck to anyone who used it for their application!
