Shield kills medusa heads?

[VernJensen]

I think it was an oversight on my part, that shields do not permanently kill the female medusa heads. I am looking to get this changed for the sequel, but am wondering, if I changed it for the original game as well (next version), would this cause problems with any existing mansions?

Second question: when levers affect conveyor belts (either direction or start/stop, I forget which -- maybe both), the

action is default room state

checkbox does nothing. Again, if I were to

fix

this, would this mess up any existing mansions?
