I was doing various freezes on the start pose of puzzle 1809, just answering chat questions. Got the crash below, no debug.txt. This one was in pull mode.

Then a similar crash in structure mode, but I neglected to capture the details. I was just assigning structures, but this time I had idealized a 4-segment helix.
