I get lots of this in the console when fighting some of the dungeon mobs:

> [19:01:10] [Server thread/INFO] [STDOUT]: [com.gw.dm.projectile.EntitySonicBoom:func_70106_y:294]: Sonic boom died!

Oops, left in some debug code. I should be fixed now as soon as Curse finishes approving the new patch version.
