When I die in survival mode, I respawn and find mobs and dropped items around me all disappear.
I can hear the sound of surrounding mobs like drowneds, creepers and pillagers, but I can neither see them nor attack them. Meanwhile, they can harm me as if they haven't disappered. As for items, it seems that I can neither pick them up nor see them.
Newly spawned mobs and items dropped after respawn are't influenced. But they disappear again when I die again.
If I quit and rejoin the world , those disappeared things may come back (to be exact, 4 in 5 times they appear again).
My seed is 4101342161604613217 and bug area are near coords 295/63/-441, and the treasure map is taken from the ship under here. The bug is, wherever I go, the treasure map just remain the same, not displaying explored areas, and the white arrow don't move. This bug isn't found in normal maps.
