Hello,
A new update (https://samoatesgames.itch.io/baking-simulator/devlog/59592/version-adc9ec5c-rel...) has been released which should hopefully mean any future crashes are reported to us for diagnostics.
The good news is @campfire I've managed to recreate your crash, so will hopefully get a fix out soon. The actual crash is in within the physics library we are using which is actually a Unity issue, however i'm hopeful we can put some protection into our code to massively reduces (if not eradicate) this crash in-particular.
Sam.
