Hostile Npcs If Classified as Ally to player wont follow the player anymore after they battled an hostile enemy

[spforce306]

if you set for example the alien grunt
or the female assassin Classification as being friendly to player
after they will combat any hostile npc for the first time
they will not follow the player anymore
i tryed to use key to unuse the follow and press use key so they will follow but it does not work
this happens after a npc that is normally hostile to the player being set in Classification to be friendly to player
they can follow the player
but if once they battle any hostile npc for the first time than after this the follow will not work anymore
please fix this as its totally very important and must have fix
