Just saw a few mercenaries ignore 5-6 hostile NPCs and went straight for me the PC.
This may have been intended but what happened was that they walked into a group of Hubologists and got GIbbed by nades and SMG's.
I didn't even have to move and got to loot a few of the bodies myself.
When there are multiple hostile groups sometimes they both run towards the PC which is cool with me.
This may be a bug but it seems like they're coded to go for the PC more often than other NPC's, This AI can be exploited when there are both hostile and friendlies on a map by just moving in a circle and letting the NPC's do the work. I've even exploited this on RT before so its no a TB only "exploit".
