I was editing a collapsed graph, and deleted some nodes. I undid the deletes and everything came back. I went up to the event graph, and saw I had a few errors popping up. I compiled to get rid of them like normal and the engine crashed to desktop.
Tried to open my project again from the launcher and got a crash, I crash every time I open the project. I really need to try and get this back.
