My party recently finished SoA and immediately moved into ToB. After dispatching Illasera with no problems I was transported to the pocket plane where Solar introduced herself. The conversation started off as it should (I think, it's been a few years since I played ToB) but she then made reference to me having defeated Yaga-Shura, at which point the Gorion/CHARNAME's mother sequence takes place and second trial door was opened. Sarevok did not appear, and there is no way to complete the first trial. After completing the second trial I cannot exit the pocket plane.

I tried several reloads, altering and removing mods I had installed (Fixpack, UB, Questpack and Kelsey) with no sucess. I CLUAconsoled Sarevok in to try and trigger the first trial but his only dialogue was something to the effect of "I've been waiting for you" with the dialogue ending when I click to continue. This bug does not occur when I started a new ToB game, and everything proceeded as it should.

I was hoping someone has encountered this before or could suggest a solution to this problem. The only thing I could come up with was exporting my character then creating a new ToB game and using SK to edit the NPCs to their current level/inventory. Obviously this would be annoying, and could potentially cause problems with Jaheira's romance, Anomen's status, and would mean I would have to redo/ignore WK (I'd done everything but Demogorgon).

Can anyone help with this bug, or alternatively help me set up my new ToB game without ruining NPC interactions?

With your reloads, did you try reloading the final autosave from SOA? I believe you would have to re-do the final battle against Irenicus, but it might be worth shot if you haven't tried it yet.

Yes I tried that already :(

I'd recommend reporting it in Fixpack's forum at forums.gibberlings3.net - if you can replicate the bug with only Fixpack installed. (Because it works fine in the vanilla game, and I haven't seen it reported before with UB/QuestPack - and Kelsey, being an NPC mod, shouldn't be interfering with this).
