In the beginning the upkeep seem to be working correctly but later in the game I noticed some building not being maintained. So, I checked my builder force, resources and played around with adding more builders but nothing helped to get the buildings repaired.
More and more builders are doing upkeep on fences and skipping some of the buildings.
I saved and restarted the game, seems this helped to have some buildings maintained but some still are not repaired.
In the screenshot one Apairy got condemned and another building (right corner) still not repaired BUT I noticed sometimes a builder going to the building showing as upkeep and leaves after some time but the building never gets repaired.
In my city I noticed that buildings are not maintained through builders but through the normal workers. Though having a decent workforce might solve the issue.
Hi Trin, thanks for the feedback. My laborers were around 40 so should be enough. Builders are doing maintenance but can happen when no construction order in queue they switch back to laborer till they get a construction order again and will switch back as builder.
Maintenance for most other buildings were done correctly and with a reload of a save and relocate/clear of some buildings I was able to solve it. Will monitor if it will happen again with some buildings.
