Issue:
While in a hardcore survival world in I observed item frames (and their contents), an armor stand, and nearby villagers go missing (or become invisible) upon reentry to a nearby bed spawn when coming from the End.
This does not seem to happen during normal bed sleeping, or when the bed spawn is very far from the item frames, armor stand, and villagers.
I have not tested for this bug in previous snapshots or in version 1.13.2 or lower.
To duplicate:
Create a new world, survival mode with cheats, any seed
Create a simple box structure
Within and along one of the interior walls, place item frames with objects, an armor stand with armor, and villagers
place a plain white bed 4 blocks away from that wall and parallel to it
/locate the Stronghold
find the End Portal and activate it
enter the End
approach the End Dragon and allow it to kill you, OR kill the End Dragon and return from the End Exit Portal
Upon your return to the Overworld bed spawn, you will observe that the item frames with objects, armor stand with armor, and villagers are missing. Although you may hear villagers.
This is temporary, to correct the problem save and exit the game, then restart the game. The objects and villagers will be present and visible as expected.
