Converted a bb1 doc to bb2 and saved, at some point crashed, now all the blocks I converted to clones in bb1 come up as blank untitled instances and make the game crash. Frustrating as I have a lot of blocks, I will try to send in a bbdoc this week to support but wanted to see if others have run into this. I have reproduced this a couple of times so it is not a one off thing. Lesson reinforced save save save lol cheers
