Lava tries to place fire at Y 256

Based on 1.11.2 decompiled using MCP 9.35 rc1

The bug

Lava tries to set blocks on fire which are at Y 255 which means it tries to place fire at 256, which is not possible. This cannot be seen with a vanilla version.

Affected method: net.minecraft.block.BlockStaticLiquid.updateTick(World, BlockPos, IBlockState, Random) if random integer is 0
