Hi. I started a project and worked on a level in UE5.0.3 and later worked on the level in UE5.1. When I opened my project again in UE5.0.3, the level I worked on disappeared. My project exists, but the level is completely gone. Should I update to UE5.1? Will the missing level show up after updating?
Thank you.
Hey there @ninalv! Welcome to the community! So when you migrate a project to 5.1 it makes a copy of the entire project instead of just migrating (for safety reasons in case it fails). So you were working in that copy. Relaunch 5.1 and you should see the 5.1 version of your 5.0.3 project in the list. They aren’t linked at all. So you could migrate the 5.0.3 changes to the 5.1 project if you’d like, but the reverse is a bit harder.
Either way the gist is that I think you technically made changes in another project altogether!
Also try this script if you need to downgrade a project, if it is your only copy.
I ran into what I hope is the same thing, and the fix ended up being renaming the level. Before migrating the project, if the level in question matches the name of one of the default UE maps that comes in Starter Content, change its name. Then do the migration. You might have to reload the level you desire and set it as the default in the project settings. This happened to me with the Minimal_Default map until I changed the name. It makes me think the default levels will overwrite any maps with their same names.
