... Great, that helps a lot. Does the problem go away if you enable "Show dot files" in the Drives tab of winecfg?
Yes, that did the trick, thank you.
Huh, I'm surprised that helps. Can you check and see if the game's save files (or possible the directory they are saved in) start with a period (.)? It may be that this code path is somehow being triggered in a way that it should not be (the point of the patch is to consolidate the behavior so that it's applied universally, rather than marking files hidden in some code paths but not others, but it may be that there's a case where it's functioning improperly).
There are no dotfiles anywhere in the game directories including the savegame dir. There are, however, these files beginning with the exclamation mark (!) in each of the save game directories: !main.nsg. E.g. output of ls -a -R:
./SaveGames/SP0: . .. location_0.nsw location_1.nsw location_2.nsw location_7.nsw '!main.nsg'
Could this character (!) in front of the filename cause the problem?
