Unknown Packaging Error and Frequent Editor Crashing

I’ve been working on a project for a game jam, and everything as been very stable and working flawlessly until recently. The Editor crashes frequently, usually when doing simple things in blueprints. Ever since this frequent crashing I have also been unable to package my project. The only reason I could think of causing this was Force Deleting map Build data, as I was having lighting issues with it (I am using models without UV’s so I have to use movable lighting instead).

Would recommend you try to migrate your content to a new project and then try again.

Dang. Thanks for the response, I’ll try it out.

Yeah this has happened to me before in the Blueprints.

This usually happens when you delete some blueprints from project and builder tool still tries to add them to the packaging process.

Do you think re-building everything could fix it?

I seem to have fixed the issue (at least I can package now) building the level giving out errors did not fix the issue, however deleting it entirely did. It wasn’t really in use anyways so it isn’t too bad.
