On vanilla + random mode with seed 596050, the flamethrower spoils into the copper cable shortcut (not the copper cable item), which in turn spoils into a red chest. Also, the lab spoils into the discharge defense remote, which in turn spoils into a gate. I was only able to test the cable shortcut to chest and the lab to discharge remote, and neither of those spoil paths crash the game or anything. Still, I assume it's not desired behavior that one can, among other things, use the shortcut buttons to generate items free from the void.

This is indeed not intended behavior we clearly didn't catch all those edge cases. Thanks for the info!

Happy to help :) It's a super fun mod so far, and there will be a video about it sometime in the next several weeks!

It should be fixed. We don't know how many people have completed runs with this mod, so if you do we would love some feedback!
