When moving about and flying to a higher ledge the dragons will commonly hit the side of the ledge, grind against it for a few seconds, and then give up and float to the ground. Normally this wouldn't be as much an issue, but I'm playing on a skyblock map, so this means they commonly commit suicide.

This may be the same problem as Issue #35.
