Hey, recently, I tried to do something with SOAP, and I typed "!set ctype soap gun" and then Powder Toy crashed. I've tried it twice, and it crashed each time.
I can see Simon slapping himself in the forehead lol. Thinking to himself, "It is a buggy element. It's a test run basically. Who would try to change the ctype knowing it is already unstable???" lol.
Soap stores it's special properties in ctype, that's why messing with it will crash game. Just don't change it (it's pointless and not interesting at all).
