Unity broke the scene, hangs when started.

No, this is no “infinity-bug” on my end. It happened in the editor without touching scripts.

So… We’ve been working fast paste on a prototype for a client. Basically after exiting “Play-mode” in the editor, I noticed there were 2 instances of the same prefab in the scene (changes made to one made equal changes to the other). Confused about the situation, I removed one of them, which caused both to be removed and I got some “ID == 0” something something error. Unity then crashed (as it does 10 times a day) and now when I try to start the scene it just sits there loading…

Since this was a fast prototype, no there were no backups made yet. Is there some way to fix corrupt scenes? There is no fucking way in hell I restart from the beginning. (Yes, I am currently flipping every table available).

Thanks for the help.

UNITY STAFF! If you read this, give me a mail where I can send you the scene in question and you’ll have to manually fix it. As I said, I CAN’T START FROM THE BEGINNING WITH THIS since a strong deadline is approaching. Fix it, please.

Did you try deleting your Library and Temp folders?
