Im not sure if these have been reported before, but sometimes the icon doesn't get reset at midnight, and I also had a wave nit spawn ir make the spawn noise even though it said it was the right time and day to spawn them in the server console.

The only thing I can think of is that I was fast forwarding with the multiplayer mod very quickly to test iu5 Bandits NPC spawn rates.

Maybe it missed a tick or something?
