In seed 1, when teleporting to -791 ~ -11927, the game crashes. There is a mansion there that didn't completely generate which has most likely caused the crash.
Note that the world will crash one more time with a slightly different stack trace (
) when opening after finally being playable again.
Initial crash 18w06a: [^crash-2018-02-12_13.39.56-server.txt]
