This "Smooth Look At Direction" Stops Action (self Disable)
after get the alignment (Target Direction).
If me walk along a straight with a character it disable self
and at a corner it did not continue follow if finish event is none.
if target direction is changed it should reenable.
i believe this cautious is new in 1.7.8.4
me using 1.7.8.4 in Unity 5.2.3f1 (64-bit)
