Windows 10 version: 10.0.16299 Build 16299
Java version: 9.0.4
In the latest snapshot (18w19b), I seem to crash 100% of the time whenever I reach a certain area in the seed 1225964276. I attempted to have the render distance set to low and lowered all graphics and it still crashes. My guess is that the game is trying to generate a structure or terrain/biome when I approach it and that generation failed somehow and caused a crash in the process.
To recreate the crash, follow these steps:
-Go to snapshot 18w19b
-Create a world with the seed 1225964276
-Teleport to -82, 90, -1000
-Fly/walk in the negative z direction and you will crash when you reach around -82, 90, -1075
Let me know if any additional information is required but hopefully you can recreate this issue with the given steps.
