--- Comment #28 from paulo i30817@gmail.com 2011-06-30 08:59:16 CDT --- It has been narrowed down to a ASM hack part of the fixpack that crashes in wine but not on windows:
On [game folder]/pst-fix/tph/enginefixes.tph Comment (/* ... */) the 4g patch
LAUNCH_PATCH_MACRO Q_Pattern_Maker LAUNCH_PATCH_MACRO Q_Engine_Patcher
to
/* LAUNCH_PATCH_MACRO Q_Pattern_Maker LAUNCH_PATCH_MACRO Q_Engine_Patcher */
This patch fixed a original bug that reset morale of companions on rest so you won't be able to see certain parts in the game (when their morale gets really low or high).
