Earlier I noticed something really annoying, whenever i try to change the material of a part, it didn’t change it but made me have to manually click the parts I wanted to change materials of, this is something I really don’t like and I hope it’s just some random setting that I can change back.
Maybe you messed up with the settings and turned a value into true. I think it’s a setting because if it would be a glitch, then why it has it’s own icon.
