[0.12.0] Rotating blueprint (sometimes) crashes game

[noversis]

I encountered a problem, where rotating a specific blue print crashes the game.

I created a blue print of a larger part of the factorio (roughly 24 assamblers and belts and stuff, so not extremely large) and if I try to rotate it, the game crashes.
I tried whether rotating other blue prints also crashes the game, but I could only reproduce the crash with this specific blue print.

I attached the save game and the corresponding log files.

It's fixed, update your client.
