This is the same for chained creatures. The creature remains assigned to the chain after being removed (good!) but the job to "rechain" it is generated and assigned before the job to milk it is complete.

The two dwarves do indeed simply fight over the creature in the hallway.

more on this:

If you have 2 farmer's workshops with orders to milk a creature, 2 milkers can decide to milk the same creature at the same time. They will tug the creature back and forth in war over who has the rights to drain the creature's precious fluids. :D

This is still an active bug in 31.06. Even disabling animal hauling on the "caging" dwarf does not end the tug-of-war.

Still present in 31.10.

Here's a save for it. It should be centered on the dwarves already. [^]

Any progress on this? It's quite annoying when running a bigger farm (I usually have about 50+ milkable animals).

The fix seems so easy I don't understand why this hasn't been addressed :(

- add a flag to mark the animal being "being used"
- when the job is done, check the "being used" tag and unset it
- when generating "cage/restrain" job, check the "being used" flag first

seems like 10 minutes at most.

While it might seem a simple and straightforward fix to you, you probably don't know how Dwarf Fortress actually works internally, so it's quite possible that making the changes you've suggested could result in very significant side effects (such as savegame incompatibility) or even more bugs (e.g. creatures being flagged as "being used" even when there isn't any task in progress).

I think I know where this is happening.

What I think is specifically happening:

0) Dwarf 2 looking for task
1) Milker goes to cage
2) Milker releases assigned animal
3) Milker looks for assignment for animal
3.1) While milker is looking, Dwarf 2 finds loose animal
3.2) Dwarf 2 tasked with returning animal
3.3) Milker tasked with milking animal
NOTE: Two dwarves are now assigned the same animal
4) Milker leads animal to workshop
4.1) IF Dwarf 2 reaches animal before workshop
4.1.1) Dwarf 2 takes animal
4.1.2) Dwarf 2 returns animal to cage
5) Milker reaches workshop
5.1) IF Milker has animal
5.1.1) Milker processes animal
5.1.2) Milker looks for task IF Milker finds task before Dwarf 2 arrives IF Milker task isn't return milked animal to cage Cancel Task: handling dangerous creature IF Milker task is animal handling-related Milker does task
5.1.3) Dwarf 2 arrives after animal processing Dwarf 2 takes animal back to cage
5.2) IF Milker has no animal
5.2.1) GO TO 1)

Returning animals to cages is not tied to the animal hauling labor. I think this is somewhat related to 0000184.
