This bug is still not solved.

I am playing Linux version as sourcerer, 19 hours - and Its automatic gameover after fight with hummel and roehm picking the box in the crypt. right at end of act I. I even offered Rayford (not crawford, lol) cigar, he still says "well well", roehm says "shit" and its gameover screen...
Ok, from what I found out, this gotta be the worst developer ever - because the bugs reported years ago are not fixed, instead developer sends "workaround" on per-case basis.... Why, why is this even on GOG?!...
After rising issue to GOG support and contacting the developer via mail, developer has promised to look into it and release a fixed Linux version. Maybe things work themselves out.
Still no fix.
Not fixed yet.
Another month, no fix.
Still unfixed and no updates.
