Any idea how to fix this or, how I can help diagnose it? I had hundreds of these entries in my taint log last night. Is this a conflict with Elv?

Happy to provide more info, but it only started happening when I installed AngryAssignments.

I work on addons as well. Best way to drive people away from an open source project is to close their issues before looking into them.

Taint error message notoriously extremely frequently blame the wrong addon, especially when they use shared libraries like Ace. Need more info that its caused by Angry Assignments.
