In ver 0.6.1,
Pitching too quickly is one of the cause of shoulder's and elbow's injury, I heard somewhere.
- Once you pitched the ball, you won't be able to pitch the next ball in 1.5 seconds.
- Some bugs fixed.
In Minecraft, you can't undergo Tommy-John surgery even if you break your elbow.
I made this update to protect player's arm from injury.(Actually, this change is to prevent this plugin makes servers slow.)
