Update: I, still, can not get this to work. Your file works fine, I've even tried different values in an attempt to break it. I messed with the instance #, the Property ID (thumbnail grouping), added a new RK pointing to the buff and changed the BuffResKey to match, every time, your's still works. But I can't seem to get anything I create to work in the same fashion. It behaves just as before, it looks like it's going to work in CAS, but does not give the buff in-game. I'll attach my package here, maybe you could look at it and tell me what's wrong?
