I am was trying to get UAIO work on my server when i noticed some odd things.
In the uaio admins folder, it comes with an "example" of how to add admins. As most people do and should know, in the admin file, any line not to be read by the mod/plugin should begin with a ; (semi-colon). This "example" includes all groups, and isn't marked with a ; and has a steam ID. I checked the ID, and it was not the one found distributing the bad copies.
I also read the top of the file, and it says that it was created by xeroblood. wasn't hethe guy who made the corrupt file, and the one supposedly not currently in charge of UAIO.
This was with v 1.5. I am sure you will find it also exists in other versions.
