Playing an Ascendancy settlement, I acquired acacia seeds from a trader. I let them sit for a while before planting them, but as soon as I did, all of the farmers stopped working efficiently. I currently have a large settlement with 39 hearthlings, and was previously able to maintain a stable level of food with three farmers and two cooks, working 3 11x11 plots and 10 5x11 plots. I keep several additional small plots (1x11) fallow most of the time until I find myself running low on trees, so I set one of these rows to acacia saplings and two of them to oak.
Soon after this, I noticed that my food supplies had dropped a bit according to the daily update. I watched the farms for a while and saw that the farmers were only replanting crops in roughly 2/3 of the plots at any given time. They were also not harvesting roughly 1/3 of the ripe crops before they rotted. I assumed at first that the balance had shifted at some point, so I promoted first one and then another new farmer to pick up some of the load. I also placed two new vaults set only to hold food in case the problem was a lack of storage space. I tried removing and redesignating the plots that were not being planted. However, the problem persisted after each attempted solution, and food supplies steadily dropped. The citizens panel showed that the farmers were spending most of the time idle even though there was plenty of work available.
I began to suspect the acacias as the source of the problem because of the timing. I reset the acacia plot to fallow and waited for the saplings to mature. As soon as they were completely harvested, the farmers returned to working the other plots at their normal rate. As an additional test, I planted an entirely new 1x11 plot of acacia saplings, and the farmers again began to neglect 1/3 of the other plots within a day. This time, I removed the acacia plot without waiting for the saplings to be harvested, and the farmers immediately resumed planting and harvesting as normal.
Steps to reproduce:
- Acquire acacia seeds from a trader
- Activate the seeds to allow farmers to plant them
- Set either a new plot or a previously planted/fallow plot to grow acacia saplings
The farmers would continue to work all active plots at their usual rate and efficiency.
The farmers neglect approximately 1/3 of the plots, failing to replant crops in more than 2/3 of the plots at any given time, and leaving many crops to rot without harvesting.
I unlocked two other seeds acquired from the trader (golden gourds and watermelons) at the same time as the acacia seeds, but planting golden gourds or watermelons does not result in the same problem.
