Does anyone know what the problem here is?
I just re-installed BGII + Tob after my incident last week. (See my "Character can't carry items" topic.
I think the problem there laid in one of Weidu's Mod (Sorry, but i found it nowhere else)
Well, i reinstalled some mods, those are:
Shadows over Soubar + Patch V101
Unfinished Business
Virtue
Ascension + Redemption
Improved Oasis 2
Banterpacks
But after i did this, and i starting playing from the beginning, i only see Irenicus saying he wants to go to the Underdark, and nothing else in his dungeon, and i am sure you should normally get a massive fight with Improved Illyich and his powerfull Duergar party.
So can anybody tell me what i did wrong in the install.

You tried to play a save game that you created before the reinstall.

No, i played a new game.

The Improved Ilyish encounter is part of the Tactics mod which you don't seem to have installed.

Okay thanks...

Which Ascension did you install? Also, what order were those mods installed in?

Another problem may have been that you forgot to delete your override directory after uninstalling the game.

The Irenicus wanting to go to the Underdark thing means you've either installed Ease of Use, or some other mod which includes Shorter Startup Cutscenes.

Well, it works now...
