MC-213583Crash upon importing world generation settings with over 256 layers
The bug
Upon importing world generation settings that include over 256 layers, the game crashes. I've attached the settings file that I used when experiencing the issue, as well as the full crash report.
Note that the world height can be any valid height, and that there must be at least 257 layers included.
How to reproduce
- Select Singleplayer → Create New World → More World Options... → Import Settings
- Import the 213583.json
file
Game crashes
