So I imported my project from Unity 5.4 to the latest Beta (5.5 I think). There I couldn’t build for Android (filed a bug for that) and I rolled back to 5.4. Now, I’m greeted by this:
I was so stupid not to back up my project. I tried re-importing assets, no luck. Is there anything I can do to save my project, or do I have to start from scratch?
SOLVED. Luckily I had saved lots of prefabs and the project was very new, so I simply put the prefabs into a new scene. I should get into source control now as if the project was bigger this would have been a disaster.
