I have been working on a new world for months now and I decided to do a quick test upload but unfortunately there were errors that prevented me from uploading to quest. I didn’t understand the errors, so i deleted the upload. Now the option to publish to the community labs is gone.
I understand there is a limit to how much content we can upload, but I think there should be leniency for those rules when content is deleted and nothing has truly been added
if you set a world to private, it leaves community labs and you can update it as much as you want.
you will still be able to create non-public instances to test the world.
you can upload a completely different world in its place by using the same ID
once a world is in community labs you can update it as much as you want
you can read more on the VRChat Wiki
If you upload a world then delete it instead of making it private you have to wait 1 week before you can upload it again but once in labs it can be updated as much as you want
