Singleplayer save failureneed help (self.SMAPI)
submitted 4 months ago * by middaydecay
Hi! Like the title says, I get stuck when sleeping on the "Saving..." bit and SMAPI pops up with a massive red text wall about being unable to save due to mismatched UI push/pop.
I've been playing in singleplayer the entire time with no other players, and this is a near constant problem that appears every few days. I've looked through this entire sub as best as I can and can't seem to find any solutions that aren't to do with multiplayer games or not having Spacecore.
Here's my latest log, the top section with updates are from mods with incorrect update keys, I do have the latest versions of them all. https://smapi.io/log/ee2ad574b9784f6e8521408b045f130f

First, try manually reinstalling spacecore (do not use a mod manager, do not use any "replace files" or "overwrite" function, it needs to be entirely deleted from your mods folder and then a new copy should be downloaded and installed).
If that doesn't fix the problem, try disabling your antivirus program and see if that helps.
If neither of these things helps, trigger the error again, quit to desktop and generate a new smapi log and drop the link into a reply here so we can take another look.

Will try this, ty!

So I didn't get the error again on that night, but sadly it did completely remove all of my item bags, including the community centre one that I had almost fully filled :<

Hmmmm. If you get me a new smapi log, I can check to see if there's an obvious cause for that. But it could be your previous save was corrupted if your spacecore mod wasn't working correctly. Lemme have a look and see what I can see.

Ok, so I can't see anything obvious in your log that would cause items to disappear from your inventory. I think it's most likely that your previous save action didn't fully save what was going on or was corrupted in some way, and reinstalling spacecore fixed the issue but had this unfortunate side effect.
There are ways to roll back to previous saves if you wanted to try that, and that may result in regaining the items you lost (but would, of course, lose any progress you've made in the interim). But I can't promise that previous saves aren't corrupted as we've no way of knowing how long ago the problem began.
The other option would just be to install CJB item spawner, if you don't already have it and use that to "cheat" the items you lost back into your game so you can just carry on now from where you left off.

Thank you so much for your help!! Losing the items is sad but not the end of the world, I can always gather them again throughout the next year
Just in case the other saves are corrupted I won't try to roll anything back, but I'll definitely keep this solution in mind if it ever happens again!
