A random thought occured to me, is the loboshigaru fire resistance a bug by any chance? Since I thought the idea was that races with fur were all given a level of fire vulnerability, yet lobos who have fur got 1 level of resistance.

Anyways, maybe it's just in the help file or maybe it really is supposed to be that way but whatevers.

Do Merians have fur? Or for that matter Mugwumps?

I think he was saying "all furred creatures except loboshigaru have fire weakness", not "all creatures with fire weakness have fur".
