Stitched

Have been playing the GOG version of "Planescape: Torment" for a week or so now and have been loving it (Fix files, Widescreen mod, etc.) but am getting a reproducible crash in the Art Gallery in Clerk's Ward. From many attempts at changing 3D acceleration, running the game in a virtual machine, changing in-game settings, the game always crashes.

Studying it further, entering the Art Gallery and stopping any movement, the game crashes out whenever the male NPC, starting behind Yvana in the shadows, appears into line-of-sight. If I decide to run along the north part of the museum, the crash occurs at the same moment. Same problem running towards Yvana; as soon as the NPC is revealed, the game crashes.

*** Addendum ***

Repeated quicksaving and clearing out the cache and temp files allowed me to continue playing. Map file corruption perhaps?

Running the game on Windows XP 32-bit / 2 GB RAM / GeForce GTX 285 at 1600x1200 resolution with UI resolution set to 80%.
