Sale price of butterfly milk woth tools vendor in the ilmenskie mines is wrong. The vendor is supposed to pay 80%. For butterfly milk which costs 8 currants each, 50 milks sale price should be 320 currants. But he pays only 300 currants.
Ok , same thing happened with 50 chunks of berryl. Supposed sale price should be 320 currants, but it showed only 300. So maybe this bug happens only with items which costs 400 currants?
