I have recently noticed a quite annoying bug or glitch happening randomly. I went 3k blocks out front spawn to a village to get the lush cave under it and accidentally fell to my death came back to get my stuff and all mobs in the area of the village were just gone. Died in my spawn village and same thing happened. Sometimes happens when unloading and reloading your world's at a later time. Just logged back into my world and noticed all my villagers in my trading hall were gone. Some how the cats are still there though. I'm unable to record this happening randomly because it just happens whenever. Attached are pictures from my trading hall. Ive tried testing in a creative world and couldn't get anything to happen.
