Meh, not sure what I'll do yet.
But since I was asked for info: the only thing I know is that the second time (when they actually came to my settlement), it was a guy in the usual bearskin, plus a guy totally naked except for a backpack.
The first time, they randomly found me and started killing me while I was fishing, then found the settlement and started to tell me to revoke claim to live (so I don't know how much they want the claim, and how much they just want to harrass), and it was those two, plus another guy in bearskin, and a guy in nettle clothes.
(I say guy, because it's hard to tell by the sprites, as I know myself. Dunno if they were all male.)
Oh, and they were doing most of the harassing in English (well, what passes for English, "niggur" and such,) but one of the guys was sending private tells to me in Russian as well. So dunno if they're Russian and speak enough English to harass/tell me to declaim, or if they're English speakers and one of them just also happens to know Russian.
