Need some help regarding a workshop item not updating

So to put it simply, I can update the actual item but not the thumbnail, and it doesn’t give me any errors. Could anyone help?

You can only update the thumbnail by an actual update of the mod itself. The preview image field in the in-game workshop uploader is the only place to do so.

I’ve tried doing that, at which point it didn’t accept the thumbnail or the update itself- when I took out the thumbnail though the item updated just fine.

You sure you did the file path right and all that?

Yep, it would’ve gave me an error otherwise.

Are you using the Devkit uploader or the normal uploader?

Normal Uploader

Use the devkit uploader instead, then?
