Found another crasher that needed fixing, this one related to brands with an SP penalty modifier applying that modifier even to things that should never have had SP costs, like basic movement and passing. This eventually caused AIs to be completely unable to do anything, which is a big no-no.

Thanks to wizzzargh and SummerSnowman for the help with this one.
