Using the new functionality that came with the last big update you can get a certain crash on puzzle 127: Grand Challenge 8. When you try to flip the separated sheet I marked on the screenshot you get error every time. I'm attaching the pic and log file.
I've been able to reproduce the bug as you mentioned, and am working to fix the problem.
Hello,
Thank you for taking care of it. Will drop by from time to time to see what's the status of this request.
Kind regards,

Hello,
One thing that I've tested a second before. It crashes on many occasions in this area, when you try to flip one sheet. Maybe it will point you in right direction.
Kind regards,
