Hey I'll real quick say this. I decided to uninstall this mod cuz I wasn't using it at all and didn't exactly plan to... but I noticed that most of my contraptions (even ones with no things from the mod) said they needed it and then were corrupted. I reinstalled the mod and they're no longer corrupted. As someone who makes a lot of saves that have a lot of effort put into them this sucks... it sucks a lot.

TLDR: If you install this mod chances are if you make a save and then uninstall it that thing will be corrupted until you reinstall it.
