I just had a fuling invasion in the meadows. Shamans, berserkers, the whole nine yards. That was a first... ate yet another death. My wooden meadows buildings will not stand up to an invasion like that! I've weathered blobs, ice drakes, draugr, trolls, sirtlings, ... most things there, but fulings are too much. I went straight to work building stone walls around my main base.

In plains I have had trolls and wolves but not blobs... but it's probably random. Just a random thing you have to deal with. One advantage I have for my main plains house is that there's a herd of lox nearby. The dumb raiders always wind up attacking the lox and getting smashed... last raid I hardly had to do anything, the lox took care of it! :)
