Stuck in Chateau Irenicus :( Options

[kiwidoc]

First up much kudos and mana to you for all the hard work and creativity that's gone into this mod *standing ovation*

I’m having a bit of hassle getting to the Spine of the World. I’ve cleared out both floors in Irenicus’s dungeon, and picked up Yoshimo along the way. I’ve tried to use the portal in the original room, but I keep ending up in the second level, where I meet Yoshimo.

I started with the following installation -
SoA + ToB + ToB patch + BG II Tweaks (Gibberlings 3 version) Baldurdash-WeiDU v1.63 + NeJ2 v6.9.1
I’m aware that the BGII tweaks pack is extra to your recommended install. I confess to having also added 2 0r 3 extra NPCs – all from Spellhold or G3, and an extra soundest as well.

I would be quite happy to reinstall without the BGII tweaks, but I don’t want to do this if the problem is something simpler. Knowing me I've probably missed something really obvious
