Thank you for clarifying incorrect information on my part Stargazer.
I just assumed that the hotfix was an official patch from Larian.
I stand corrected.
This however makes me rather cautious of ever buying another game from GOG.
Perhaps that is a bit harsh.
Shall we say another game from GOG that is actively being patched by the developers.
See I never came across this problem with GOG before as I only have bought old classic games from them. Not a new release.
Lesson learnt.
