I have been able to reproduce both of the above mentioned in this section: "Other reported observations, not reproducible:"
To reproduce, create some sort of farm( i used carrot) and contain it with ceiling, floor, and walls on all four sides (not allowing any villagers to escape). Now place 10 villagers, 10 beds as floor blocks allowing for 2 blocks above before roof, and one composter. Then set time to night. Now just monitor. If no villagers despawned or got "lost" then the villagers would not breed as all beds would be taken. To further prove this, control the food and when a villager is lost after nighttime, close world and reopen, and you will see that if you give villagers food again to breed they will do so, because a bed is no longer associated to the lost villager even after reload.
what types of resource pack?
this most likely has to do with most of texture packs no longer show as they did before because of the new render update in 1.16.200, this doesnt mean there is an issue with MC but rather the resource packs needs to be updated after the most recent update.
