I have run into an odd bug with Prism the Sculptor at the Nashkel Mines - he's already dead before any interaction with him. I can't say for certain that this is ToF's doing, but the only other mods I have installed at the moment are Mur'neth and the BG1 NPC Project (see attached weidu.log), and I don't think either of them should mess with Prism.
When I arrived at his sculpture outside the Nashkel Mines, Prism's corpse was already lying on the ground - no sign of Greywolf or the emeralds. I tried spawning in a new Prism using the console, and he died instantly (see attached image). My best guess is that maybe ToF's updated ability score rules have caused the game to recalculate Prism's hit points and get an answer less than 1 (according to the Fandom wiki, he only has 7 constitution, which is a +0 modifier in unmodded BGEE but a -2 in 3e, and he's level 3, resulting in a total swing of -6... on a character who normally has 4 HP). But if that were the issue, I can't imagine he'd be the only character affected, and I haven't seen any other unexpected dead commoners in Beregost or Nashkel.
Any ideas?
