An additional linux issue I've seen myself is that Mods don't seem to work... Even though they should be OS agnostic with how they're made...

That's quite the same, ultimately I dropped the game because after playing with the Windows version through Wine I still ended up getting 200mb of data lost from my SSD again.
I feel like it's just an incompatibility with this game and Linux (Mint?) maybe because this game autosaves way too much a bunch of temp files are being spammed in some unknown directory or something, but I'm not tech savvy enough to be able to find out.
Fun game, but not the most friendly with Linux it seems.
