In a game with [ZERO_RENT:YES ] in the init file since the fortress was founded, when the economy kicked in, bedrooms had rent and everyone except a handful of founders and 2nd wave immigrants were evicted.
I stopped the game late at night, and the next morning noticed upon reloading dwarves sleeping on the ground everywhere.
Fortunately I have a save prior to the nobles showing up, but I'm going to lose several hours, and I hope that is enough to actually fix the problem. I've changed my Init to disable the economy entirely as well, as I really dislike the bedroom rent situation.
Also, I have stones marked for dumping to clear rooms for later smoothing/engraving; one room on a floor by itself (under my dining hall) and a new wing of noble offices have been marked for dumping for nearly 2 game years. None are getting dumped, and my idlers have climbed to over 50 (out of 140+).
To forestall a few obvious questions, I have had a garbage zone throughout (and moved it to RIGHT NEXT to the areas to be cleared after I noticed none were getting moved), refuse hauling is turned on for all my peasants and other low priority crafters. Other dump zones have worked wonderfully during this game; clearing out thousands of stones to make way for stockpiles and rooms. Why aren't they moving the stones?
