Crash
The bug
If the player makes a preset for superflat that goes over the build limit, the game hangs on the loading screen.
Example preset:
minecraft:bedrock,255*minecraft:dirt,minecraft:grass;1;

Well, Minecraft's maximum build height is 256, so when the game tries to place blocks above that, it crashes. Also, please don't give us the output of the console, but give us the crash report from
C:\Users\Logan\AppData\Roaming\.minecraft\crash-reports\crash-2014-08-18_17.17.46-server.txt
instead (the link to the crash report is always in the output). But I agree that Minecraft should not allow you to do this, instead of crashing.
Confirmed fixed; the blocks above it will have their count set to 0 (which makes sense and doesn't lose information)
