Right, I have run into a strange bug. Somehow, Aerie was affected by a "feeblemind" spell. Okay, "no problem" I thought, and dispelled it. However, awhile afterwards, I noticed that I could no longer access her sequencers from the "Special Abilities" menu... Fair enough, her Int was set to 3 for awhile, so I assume that's what messed up the sequencers, but now I have a major problem:
Her portrait still displays "Sequencer Active", so when I try to cast a new Sequencer with her I just get a "You can't use the same contingency twice"-message, or nothing happens. And since I can't access her Special Abilities, I have no way to fire the sequencers that she already has active!
I've been looking around in Shadowkeeper but I can't figure out how to remove the Sequencers she has, or enable them so she can cast them... And I think dying won't reset them, either. In other words, I'm screwed!
So if anyone has any advice on how to revert this I'd be much obliged!
It seems that dying removed the Sequencers...atleast now, I can have her memorize new ones. But the number of casts for each sequencer is "2" which is impossible, so...eh. It seems this has solved the problem, but I think it still might be bugged, I don't know...will have to test. So feel free to post if you have a better solution.
