wesp5: Uh, this looks as if the whole Python part of the patch isn't active. Did you switch between the vanilla and patch shortcuts during the game?
No, just used the one with patch.
wesp5: Where is your save game located, in the Vampire/save subfolder or the Unofficial_Patch/save folder (I hope you didn't copy it from one to the other)?
"Unofficial_Patch/save" and I've never copied files between those two.
wesp5: Have you installed a newer Python version on your computer recently? Do you get the same kind of errors if you start a new game?
No and I guess
yes. (Just an part, there are some more errors.)
wesp5: What is the date/time stamp of Unofficial_Patch/Python/vamputil.py and vamputil.pyc? Try moving vamputil.pyc elsewhere which will have it rebuild. Does this help?
Unofficial_Patch/Python/vamputil.py: Di 18 Apr 2017
vamputil.pyc: Di 06 Jun 2017
After moving and rebuilding, still the same issue.
