The game won't open when I try to open it. It says "migration failed."
I've tried following the guide that pops up on Google Chrome, but nothing seems to help.

Did you try reinstalling OneDrive? And did you enable the "Always save on this device" option for your Documents folder inside of OneDrive?

I didn’t try reinstalling it because me and my mom were worried we’d lose it. I tried to find the “always keep on this device” but the option cannot be found anywhere
I have windows 10, if that helps
Yes, that’s the one
I also tried to find and delete the “dire cosmos of nausea” world, since that’s the seemingly corrupted file (as shown in the image) but it wouldn’t let me delete it
Save data (for worlds and players) is stored in your OneDrive documents folder, separate from the game files
Is OneDrive running on your machine?

We were worried of losing everything that’s on it, not just the game files
How could I check?
What are you worried about losing exactly?
conscious-sapphireOP•2y ago
We have images and other documents saved on their because it’s my mom’s one drive, she’s just worried we’d lose them if we delete it and reinstall
There should be a white or blue OneDrive cloud on the bottom right of your taskbar - if not in the chevron pop-up menu

No - deleting the game folders inside the
SteamLibrary directory will not affect your player/world save files
Did you try finding that file in OneDrive and deleting it, if that world is just corrupted/lost?
And are there any backups you could maybe use instead?
Also, it looks like that's a save file from the tModLoader preview version, so are you needing to migrate that file, or should it just be deleted?conscious-sapphireOP•2y ago
on that cloud its saying i need to sign in again, so ill try that real quick
finished signing in again
tried opening the game and it says it is downloading the world file that was broken, so ill wait to see if that works
Yeah if you're not signed into it, it's going to throw errors if a program tries to use the files
but that only happens if the option to always keep files is disabled

okay the game did not open
Definitely tick that option on for the Documents folder if you can spare the storage space

but the file thats broken is different now
its a different world
is it in OneDrive?
what's the path look like?

ill try deleting the file
the new broken one or the old one?
the broken one
conscious-sapphireOP•2y ago
onedrive is still processing changes in the cloud in the bottom right, that might be why
ill give it a few and come back
Yep just wait until that's done

okay so its almost done and i got a message on screen saying deleted files are removed everywhere with the file of the dire cosmos world that was the broken file
so it may have deleted now, or may allow me to delete it
the game opened!!!
thank you so much
Yup
