Issue 1:
On occasion creatures that are marked to be hunted, will be marked as forbidden when they die. Ex: The creature dies from bleeding out, instead of a hunter's bullet. Ex2: A hunter accidentally hits another creature and kills it instead of his targeted prey.
What I expect:
If a creature that has been marked for hunting gets accidentally killed by one of my hunters or bleeds out because of stray bullet then it shouldn't be forbidden to haulers.
Issue 2:
You tell a worker with a low shooting skill to be a hunter in order to grind his/her shooting skill. They will stay out there until they are having a mental breakdown if they keep on failing to kill the creature.
What I expect:
When the hunter gets hungry or tired, he/she should go eat or rest. Rather than stand out there going insane from starvation and lack of sleep.
Issue 3:
Hunters will quite happily fire their guns when another hunter/worker is passing through their line of fire. Injuring or killing them on occasion.
What I expect:
When a worker gets in the way of the hunter, the hunter should either wait for the worker to pass on by before firring or move to a different location before shooting again.
Issue 4:
Hunters will get as far away from the prey as they possibly can before shooting. This lowers their accuracy significantly.
What I expect:
Get the hunters closer, no further than half the gun's effective range.
That concludes all the issues I found with the hunting.
