Hunter cant get to his prey's corpse if its near of a mech cluster

[Alenerel]

A hunter downed a deer near a dormant mech cluster (about 8 tiles away) but when he tries to get the corpse he starts to flee cause he got near it. Then tries to get the corpse again, then starts to flee, again and again until he goes do something else.

He should either get the deer's corpse without problems or never hunt something hes not willing to pick up.

Also this have happened 2 times with one single mech cluster.

This is correct behaviour since shooting the animal was being out of range of the cluster.
You can temporarily change that by switching to Do Nothing in the presence of threat.
Just make sure to revert that change.
