Nick, it seems like there's been some MBAM conflict of late between it and some of the AVs. So I thought it might be beneficial to start pushing my exclusions onto systems, much in the same way you're already doing with offline definitions but applied more universally.
"C:\ProgramData\Malwarebytes\Malwarebytes' Anti-Malware\exclusions.dat"
I've confirmed this is the file by checking its timestamp after I'd just added an exception.
Side note: I would absolutely love to be able to import/export my general settings for new installs (e.g. increasing the updates to 8hrs, adding a couple of scheduled scans, automatically check PUPs) but I have not yet been able to figure out where MBAM saves this info.
