Steam Cloud - Unable to Sync

[HumanGoing]

For about the last week, I keep getting this "Unable to Sync" error pop up with a warning that Steam was unable to sync my saves with steam cloud. This is a fairly new problem and it happens whenever I try launch the game (both modded and unmodded). I get this error on both my PC and on my Steam Deck

I have tried manually re-syncing, and uninstalling and reinstalling the game, but the I still get it. Any suggestions?

Just guessing, but assuming your PC runs Windows it might be that the saves are different between the Windows and Linux versions of the game and it's creating some problems for the sync. Might be solved if you force the game to run via Proton on your Steam Deck.

Good suggestion, that seems to have contributed to resolving the issue.

I had uninstalled it from my Steam Deck already, but I was still getting this pop up when I launched from my PC. But I tried reinstalling on the Deck and forced it use Proton. Now it will launch on my deck with no pop ups, which is perfect.

Initially, I was still getting the pop up when I launched on my PC. Even after uninstalling and reinstalling there. Weirdly though, after some combination of reinstalling/uninstalling and even trying to launch the game on both devices at the same time, I have stopped getting the pop up in both places.

So it does seem like your idea about a conflict between Linux and Windows versions may have had something to do with it. Thanks!

The thought only came to me because a couple other games have similar issues, though it is strange that it only started happening recently for you. It's possible everything here was a fluke, because I've had cloud sync act up for no reason when playing on multiple OSes with other games before, even Proton games, but it'll just randomly correct itself at some point.

If it acts up again I'd try deleting the saves locally and letting it recover from the cloud on both devices without launching the game, as I'm now leaning towards that being what actually fixed the issue, since switching to Proton would result in it reacquiring the saves, while reinstalling doesn't.

This sync problem seems to just be a common bug stemming from Linux and Windows play on any game. Maybe related to filesystem differences, who knows. Regardless, happy to have helped.
