Thanks Michael.

Sorry for naming the assert a crash. I'll differentiate between them from now on.

I accidentally selected the Endpoints mode a few times while trying the different Rebuild modes for circle curves. Solving the assert will make MoI more foolproof for absent-minded people like me. ㋡

I just tried the Rebuild option in the DistortCurve script again, and this time it worked fine, so that must have been a specific situation, maybe a wrong selection.

Thanks,

Metin
