The server should always send SMSG_SPLINE_MOVE_SET_RUN_MODE when a creature flees.
[z2439] Don't do periodic heal ticks if the target is already at max health.

Areatable may contain duplicate exploreflag, so to have best value someone assumed the best way to be sure its correct value is to check if map_id of that area entry  is the same as the one where player is.
