@mexxico I did detect a major problem, the hunt down group of bandits quest from villages if left undone can cause a snowball effect that can cause towns prosperity to go to 0. 3 of the 6 Khuzuit towns are now near or 0 in my playthrough around day 1200. Especially when 2 villages get it at the same time. The quest gives -5 prosperity so when 2 villages from the same town get it that is -10 for quite some time and it snowballs so the lower prosperity gets, the less food they have which lowers prosperity for less surplus food so it just keep getting worse and by the time the town in under 400 it is so hard to build it back up. In my game 3 of the 6 Khuzuit towns are now under 1,000 prosperity so selling to them is almost impossible since they have no money. and also have very little good to sell with low prosperity and they are the best place for chees and butter and to sell grapes and olives.
