The problem with the bears. (The Long Dark)

All good. At me such problem: there are No bears on the locations. Play on the level of "Stalker" Lived for about 36-38 days (not exactly say, did not pay attention). Want to get a skin of the bear to create a sleeping bag and coats, but I somehow, again, does not appear to be bears. wolves, deer and rabbits are very much welcomed, but the bear didn't find one. I read on forums and other places about their dens, like, looked and found none there. The bug is not likely.

It may have some number of days to live, so the bear appeared in the world? Help, thanks in advance for your answers.
