So, I was finally able to fix this bug under custom Proton build: https://github.com/PSzczepanski1996/proton-ge-nostale
The patch that fixes the game is here: https://github.com/PSzczepanski1996/proton-ge-nostale/blob/master/patches/wi...
As I mentioned in previous issue the bug is caused because NosTale checks memory regions and Wine places system libraries differently than Windows in the RAM. I'm not doing any Pull Request right now since the issue should be discussed and Wine get's into freeze phase - this thread is place for talking about it.
