Unfinished Business Bloddscalp problem

[Ode to a Grasshopper]

Hey all, I'm finally doing a complete BG series run, am in early BG2 with the following mods: SoA, ToB, ToB patch, G3 Fixpack, Dungeon-B-Gone, Saerileth, Kivan, Xan, Unfinished Business, Level 1 NPCs, G3 Tweakpack. This is my first run with UB and it's pretty sweet, but I'm getting ready to head off and rescue Imoen and can't access the room where you meet Renal Bloodscalp - when I try the game just crashes. I've tried from inside and outside the Thieves guild and it's the same both times, and more recently tried a full reinstall with the same result, so what I want to know is:
Has anyone else had the same problem, or do they know if there's a bug like this in UB?
and
Are there any significant UB bits in the room, so if not I can just uninstall it for that section and reinstall after wards?
Cheers.

Welp, I got in, and rthen went and saw Linvael, and when he passed me the magic items it crashed then...
This kinda sucks.

Fixed with a massive reinstall with thr latest of all the above, and skipping on Auto-pause dialogue.
The party's just got into Spellhold.
