Issue description

I have made a minecraft mod that adds trees to the game.
to make the trees generate i used the procedure on generate for structures, and the trees generate fine, but the game locks up soon after. the console will say things like
"[Server thread/WARN] [minecraft/MinecraftServer]: Can't keep up! Is the server overloaded? Running 87707ms or 1754 ticks behind" 
the screen turns gray and JavaTM SE binary has stopped working.
about 5 whole minutes after the game locks up it finally crashes and outputs this report.

-on some digging on my own I figured out it had something to do with leaves decaying-
