End Exit Portal Move

In August 2020 players noticed placing the four End Crystals on The End exit portal did not start the dragon respawn sequence. The four End Crystals sat on the Bedrock and did nothing.



Earlier on Daenningas visited The End and found some obsidian next to the End Portal. The End Portal looked duped on top of itself due to a game bug. The unneeded bedrock blocks were removed and the issue was forgotten, until it was released the Ender Dragon would no longer respawn.

Opening the level.dat from The End world folder with NBTExplorer, it was found the exit portal blocks need to be on Y 59. Daenningas used a test world to break that exit portal in the same way with WorldEdit. Once that was done he came into the server and used WorldEdit to move The End exit portal into the correct position on the server. The exit portal blocks were sitting on Y 62, moved down 3 blocks.



Once this was done the dragon could once again be respawned.

Retrospectively, no regular players as well as Daenningas have a photo of what the exit portal looked like in the broken state.

This is a significant server event, as if this issue could not be resolved there was a very real possibility of needing a map reset or chunk removal. A last resort fix.

Reproducing the break on the Enchanted Sword test server. You may not be able to detect the portal is in the wrong Y position, but it is. The four end crystals are placed in the correct location, but do nothing.
