Mirror dynamics problems

Bug reports
Every time I try to duplicate a part or even mirror the part will crash and close the program. The last update is giving me so many problems now. Also in the forms plane that allow you to mask the part cannot disable mirror strokes. It’s always on making imposible to mask the part I’m blocking. Program closes so many times that frustrates me loosing some work if I don’t save. No more than 3 steps so no big. But mirror objects.

For triplanar masking, the symmetry button will be reintroduced in the next release.

However, for the other crash I suspect you simply run out of memory so I can’t do anything about that.
(Unless you can reproduce a crash with a low poly scene).
