Currently, fragmentRadius (of 4 if not set) only works if the missile is close enough to an active enemy, whether it is a target or not. If the enemy is dead or the target is not an enemy, then the missile will not fragment if the target is within fragmentRadius. The missile's target should be included in the fragmentRadius check.

I found a couple of cases in which the missile does not fragment even though the missile's target is set. I fixed this in 1.9 Beta 2, but I'm not sure if I handled all your cases.

Please re-open if not.
