Infraction Group permissions not working anymore

[Falkware]

Let me first explain what we are trying to do. We have a special room set up called "Purgatory". No member group can see this board on the forum.

When a user repeatedly misbehaves and reaches a certain amount of infraction points they invoke an infraction group that assigned them to the PWND group which overwrites his or her permissions. Now all they see is Purgatory where they can freely post to communicate with the admins/mods. Once the infraction level drops below the threshold they return to the general population of boards.

This was working great initially but it no longer works. The user loses access to all boards, and can't see Purgatory. We've had vbulletin check it out and all our permissions and settings are correct. They suggest an add-on could have caused this.

I installed vbexperience for a period of time and then removed it and I fear this might be the culprit but I can't figure it out. I've used the SQL compare tool on here to compare our tables to a stock install and I can't see anything except some minor mods for media embedding, mood, separate sticky/regular threads. I've uninstalled most all mods and they don't strike me as the ones doing this. vBexperience would make sense cause it touches basically everything on the site.

Has anybody run into this before and if so do you know how to fix it?

One more thing. If I manually add a user to the PWND infraction group they do see the jail board so the permissions are working properly, just not when used as part of infractions.
