Party or solo: Solo

Describe the problem: Single Bandit NPC that does nothing but still can be killed, looted an also provides with exp. Becoming a dummy. It does behave in proper way which is happened for me in 1 of 4 cases. I think the NPC behavior some how depends on from what direction character is coming to it.

What was the expected behavior?: This single bandit should behave just like the other same bandit npc.
