You're right - the parser is barfing on some of the stock formulas. I was apparently testing the wrong data file earlier.

I've got the saving part fixed so you can still allow saves and I've fixed the plague bomb formula problem. The min/max damage formulas are a bit tougher. For some reason, the parser is thinking that

(50 + (([%Level%] - 1) * 5)) - ([%Range%] * 0.8)

is two parameters. If I surround the whole thing with parens, it works fine. But this definitely does seem to be an issue with the parser. I'm looking into it more now.
