No problems with the blueprint tool so far, however... 2 crashes while using other LUA recipes, in other words the most common and persistent crash for the monomer mutatable puzzles is still ... prevalent. No change either on the game_dynamic issue.

Attaching latest mac crashlog, script log (if it's there for both) and log.txt. (eventually, see below)

This crash also has crashed my dock, apparently. This could be problematic as a hard reboot is usually the only fix.
