"Some updates failed. Check your log.txt for more info." Error

[rancid wagon]

I'm sorta new to the celeste community so I don't really know if this is a common error or not but I was making a new file (with an already existing file) for making celeste maps (in Celeste.Mods) to better organize map making and I put some of maps in the file, then tried to open the game and it popped up with this error message so I tried to delete the file to possibly restore the noncrashing celeste, but now it just has that error every time I open the game. Just tell me what to possibly do to fix the situation. Tysm for helping ;P

There are two types of logs; crash logs and log.txt.

Crash logs are generated when you see an "Oooops! :(" crash handler screen. They contain extra information which regular logs don't.
To access those, there's a button that says Open log file folder, which should take you to where they're stored. Make sure to grab the latest one!

For more subtle issues, non-crashing problems or other miscellaneous stuff, log.txt is checked. To find it, do the following:

• Open Olympus.
• Press the Manage button in the Installations panel on Olympus' main menu. (it's to the left)
• Press Browse to open the Celeste folder.
• Look for the file named exactly log.txt inside that folder. Do not grab error_log.txt or look into the LogHistory folder as those are not the log.txt you're looking for.

Your username may sometimes show up in those logs. If you're concerned about that, remember to censor it before uploading. Every text editor should have a replace function, commonly opened with Ctrl+H.

It will be helpful if you find the log.txt it mentioned and let's check it for more info.

And this seems isn't a real crash that prevents you from running the game.

You also can search for e.g. "auto update" in Mod Options and turn it off. this should fix it. btw do you zips your mod?
