I, without a doubt, have trouble getting Piestskin maps a BTN since the last maintenance. Since day 1 of 2.1 I it has only taken me <5mins to snag one but now it is around 30-45 mins of farming until I give up and grab a boarskin. It seriously has only been this way since the maintenance that these terrible farming times have started. Maybe they saw how many and how cheaply they were being put up on the market board and decided to fix that? I can confirm that at least three other BTN in my FC are dealing with these long farm times and only for this week. Fishing seems to remain untouched in terms of getting a map quickly.
