The bug
The game crashes with java.lang.ArrayIndexOutOfBoundsException during world feature placement / decoration. I am unsure of the cause of this issue. It was showcased in this video by Phoenix SC, and I could reproduce.
A crash report is attached.
How to reproduce
- Select Singleplayer -> Create New World -> More World Options...
- Change World Type to Superflat, and select Customize -> Presets
- Select Tunnelers' Dream
- Change the preset code to
100*minecraft:stone
- Select Use Preset -> Done -> Create New World
Crash
If the game does not crash, you may need to try it a few more times.
