I cannot clearly say why this appeared… My villagers had just finished eating a meal at their tables and chairs… (btw a villager was sitting above the chair instead of on the chair, the others were sitting ok)
This one occured after I saved my game, exited and restarted the game where I had left. It occured immediately after loading.
This bug occurs if I click on the “Change vision mode” icon to display houses without their walls and roofs and if I move the view with the keyboard: strangely, part of the roof of the second house is displayed. It disappears if I reclick on the icon again, but reappear each time I move the view.
In r130 houses are perfectly built !!! Thanks for the bug crushing guys
