0000374: Deconstructing a restraint (chain/rope) with an animal tethered ends up leaving the restraint on the animal
If you:

- construct a chain
- assign an animal to it, wait for it to arrive
- deconstruct the chain

Then the chain ends up attached to the animal's upper body and is unavailable unless you explicitly find and dump it.

This occured in the previous version(s?) of the game as well, so not a new issue.

Try that in real life with a dog. What happens? ... You get a dog wandering around with a chain attached. I think it's a feature, not bug. Or at least think it should be a feature.

you should however be able to 'build' the chain back to the ground without going top the pain of finding it and dumping it, if it is a feature, (to be honest I like it as a feature, it just needs fixing to be able to use the chain still.)

What Chromasphere said. It sounds normal to me and its easy enough to remember to unchain the animal first.

This was considered a bug in the old version, so it's still a bug now.

# 000177 □ [dwarf mode][jobs][animal handling] if you remove a chain building with an animal attached, the chain stays with the animal

This still occurs in 31.12

For chains that are remotely deconstructed using a lever, this is quite obviously by design, since the game is explicitly inserting the chain into the unit's inventory - logically, triggering the mechanism causes the chain to detach from the floor.

The fact that it happens for manually deconstructed chains as well is probably just due to it not having special logic for that case.
