Affects Version/s: 1.16.20
Fix Version/s: None
I have tried searching here but got no matching results, so I believe it's a new bug.
When an End Gateway generates on the outer islands (by traveling through one on the main island) and happens to generate through chunk borders, the gateway is generated incompletely - only parts inside the chunk where the gateway block is at generates.
- Use this seed to create a world: -261618638
- Go to the end and kill the dragon (can be done by /kill @e[type=ender_dragon])
- A gateway should generate on/near the -Z axis
- Go through the gateway
- The gateway on the outer islands is cut by chunk borders.
Note: The exact position that the outer-island gateway generates may vary slightly so it's not cut by chunk borders every time; if this happens, delete the world and re-create one using the same seed, until you see the incomplete gateway.
