The issue is that while I can load "manually"... the f8 key doesn't seem to function... and when it does it crashes the game.
Just tried this now. Pressed 'f5' (quick save works) pressed 'f8' and it loaded (so that worked too).
Well holy shit it did. It must've been something unrelated to your mod. I apologize.
Some others are reporting it too. It might be related to 4 people being online using it or something. I don't know/unsure. I don't even touch the quick-save/quick-load function, so it should simply work as normal.
