Bound mortar fixated on automaton storage.

Out and about in the desert Gauntlet realm at night, a pack of bound spawned near to my location consisting of 2 mortar units and a lamplighter.

The lamplighter and one of the mortars attacked me as normal, but the other mortar unit started to attack a nearby automaton storage pillar instead.

After killing the two threats i was able to walk right up to the remaining mortar unit who seemed oblivious to my presence. It just kept firing at the storage pillar repeatedly even as i attacked and eventually killed it.

It's a very minor issue but i'm assuming this is a bug and not intentional behaviour.
