p13 found by Sylvani at Discord. There is probably an occurrence in apgsearch one of the stable 2TFL rules, since it works in the 1TFL B3/S236c. It hassles two copies of the object hassled by the p26.

Spaceships and partials are always returned oriented north, so you just need to check that the output orientation is correct.

qfind needs OpenMP for multithreaded searching, which is really an essential part of qfind. I'm assuming based on the presence of "DARWIN" in your error messages that you're on a Mac. In that case you will need to ...
