This error is absurd, I played for hours on "the end", so when I entered the main island portal I ended up dying, life full, diamond armor, Peaceful game, but when entering the portal, I died of a fall, before going to the overwatch dimension, I only received my xp, nothing I play through the portal, it reaches its destination, and with that I stopped playing Minecraft, Everything I achieved was lost, because after my death, nothing appeared.
