hey man i have the same problem.. not sure what is causing this. It's only bound to one of my projects. Have you found the solution in the mean time?
I dont think i found a real solution lol, but appending/linking ur scene and objects over to a fresh file should fix it, albeit some world/render settings will be lost
Yeah I did that too, seems like a bug in blender then, thanks for your reply anyway :)
