[Bug 47129] Caste Siege/Ballerburg crashes on start

https://bugs.winehq.org/show_bug.cgi?id=47129

--- Comment #9 from Paul Gofman  ---
Also, I can now reproduce very similar looking crash with the demo when I start
it with the current directory not being current (the same mov instruction
dereferencing NULL with 0xd8 offset, crash address is different but close,
while the executable is likely different for demo). I suspect it might be the
culprit, can you please make sure you run the game with current directory being
the one where it is installed (where is the excutable, and where you see the
Data directory)?
