After defeating an entire raid, villagers stop sleeping and freezes in place just to despawn when logging back in. The one that stays no longer have the beds they were initially assigned to, the day before. Here I am after 3 days of villager organization just to have all my work destroyed. About the villagers ''despawning'', it may have been a simple misfortune that they, for a reason, died when I wasn't looking (despite the numerous iron golems guarding my village and still having 10 casualties to a total of 13 villagers) but the beds that are assigned to the villagers are definitely changed after a raid. It's not a major problem, but for people like me trying to keep things organized in their village, it's fairly frustrating as we all know how villagers can be stubborn sometimes.
