I experienced this issue as my village grew larger, around 200+ people. I have about a dozen farm, each with two people. This worked as I grew through 25 years. However, very abruptly, at year 26 they stop working.
Their task is set to ‘wandering: unable to work’ and they stand in the fields despite the fact that they should be planting. They also won’t harvest, though the game thinks there ought to be something to harvest because it will pop up messages about the food rotting. Mousing over the icon on the fields says that the full amount that would have been harvested instead rotted. The notification in the top left displays the total number at the end of the year. Visually, the fields are clearly not planted but they become planted if I reload. These are then not harvested, leading to more rot.
I’m not sure if this is because the village is larger, because I have too many farms, or something else. I tried both saving/reloading and quitting/restarting but the bug persisted.
I’ve attached a link to the zip file, since it was too large to upload here
In that, autosave 2 is at the 25 year mark. They finish this crop fine and have issues the following year. ‘Finish but ded’ is when I ran out of food much later on after multiple years of the bug, while ‘Bug confirmed =(’ is after I quit and replayed a year from Autosave 2 with the same bug.
Please let me know if there’s any questions or anything like that!
