Fleeing monsters

[ryula2606 1]

I was hunting Ol Mahums on Fortress of Resistance (Partisan's Hideaway)

Monsters there happen to flee from time to time when they are losing. Once they manage to run away, they stop at a designed spot and just wait there, for ever.

I remember that fleeing monsters used to go back at their camp and gather other monsters to beat the player (a pretty painful sight), but these ones just stay there, and if you attack them, they won't even defend themselves, not even after a few hours of "resting".
Maybe this also happens with other fleeing monsters which i know of, i'll check later.
