Npc’s continue to complain about being tired even when their fatigue is very low, they still refuse to sleep when set to sleep when tired until they are exhausted. They even complain about being tired as soon as they wake up with -25 fatigue.
The PR that will fix it is waiting for merge.
The problem is my bad copypasting resulting in fatigue check missing. They should sleep when tired, but will complain even when not tired.
