Reviving this thread as it definitely is not being caused by the satiety bonus from meals or full satiety cells. Only started happening to me after installing a couple hunger system mods (obviously, I assume this is where the error is coming from). The mods are: ExpandedStomach-1.2.4, SleepNeed_2.0.3, HungerPatcher (disabled), HungryWhileInjured, Hydrate or Diedrate.
@ShnitzelKiller did you ever find a solution? I can't figure out the mod/configs that have caused this and nothing changes through my testing.
You can see the visual error from this bug in the satiety bar in the images below, it jumps between the correct indicator to a seemingly overlapping bar/cells. This happens multiple times a second. You can also see the max satiety jumps from 1500 to 2000 as well, this happens in tandem with the bar glitching out.
Any ideas would be greatly appreciated!
