Has anyone encountered similar? (S.T.A.L.K.E.R.: Clear Sky)

I decided, then, stalmach ers repeat. Come in a fishing village, beat off the attack of the renegades. And suddenly all the same fishing village is attacked by a pack of dogs! Dogs! Which is surprising, you ask? And the fact that dogs do not have the right to appear in the marshes prior to the first appointment of the Cordon. And I haven't visited! Anyone had one of these?
