Well, I was making a playthrough after some time off TSL, installed everything no worries, no errors. Went through Onderon, no problems, then went to Dantooine.
in the "Finding Vrook" quest... he isn't in the cave, neither any of the mercenaries.
I'm using the USM with Stoney's patch, and i recall seeing a report about this bug, don't remember whre exactly.
Is there a way to solve this?
EDIT: Nevermind, found the fix at deadlystream, problem solved
