Long-time Thief fan, newborn at foras.
I encountered a problem in fully updated Thief 2 (1.19, the latest TafferPatch) purchased from GOG.com. While the first two missions were working completely normally, the third one - Framed - was buggy as hell.
Objects were moved or misssing (no ladders sometimes, some doorways would appear completely black until you approach them and then a door appears). There was weird lighting from no apparent lightsource which made the mission a bit complicated. Torches which were casting no light whatsoever, and dousing them did nothing. Torches and lamps which were casting light, but dousing them did not kill the light. Light-switches on the second floor offices that would change the indicator of the ceiling lamps from 'off' to 'on' (the bulb would go white or dark), but the ambient light stayed the same.
I tried to reinstall the game couple of times, both clean reinstall and just a normal one, with or without patch 1.19 (on GOG named 'global update') and TafferPatch. Didn't see any improvements, apart from the fact that starting from the last reinstall when I load my saved game, the lights from the torches that I've doused dissapears (but dousing other torches does not kill their light still).
This may have something to do with my machine, but then I'm wondering why did the things function properly in missions 1 and 2.

Any thoughts on this?
