[2023] MOVED: Forced update breaks my game

Originally posted by YangWenli: Steam just forced updated my game minutes ago and broke all my saves, it's only a 2.6 MB update so it can't be that important but no matter I can't revert it and now +70 hours of gameplay are lost

We haven't pushed any updates since the Elegance of the Empire update 2 weeks ago; if your game updated it was almost certainly workshop content.
