-Removing the wall also does not remedy this problem.

I've had this happen with chopping wood. Wasn't sure what was causing the issue. 40.03.

I don't think it's so much the walls as having their path removed.

Was able to reproduce with bridges as well - adjusting title accordingly.

0.40.04, Linux. Save at http://dffd.wimbli.com/file.php?id=9140 [^]

Upon reaching her first birthday, Limul Searchedshoots discovered her nakedness and assigned herself a "Pickup equipment" job -- but never moved from the spot where her mother was carrying her at the moment she stopped being a baby.

Limul is standing in the barracks (hotkey F4, or you can use the unit screen). The job is visible on the job screen, and you can see that she's got her eye (metaphorically) on a (giant cave spider silk left glove). There are three such gloves -- one owned and worn by a miner, and two sitting around. By forbidding one, SIGKILLing the process, restoring from the save, and forbidding the other, I can see that the one she wants is on the up/down stairwell at Z=122 (-27 from the surface), and not the one in the smelter at Z=121 (-28 from the surface).

Neither of these gloves shows her (or anyone) as the owner. Forbidding the glove that she wants causes the glove to be removed from the job screen, but does not cause her to cancel the job, or to seek a different item. The job itself cannot be removed (the r is greyed out). Saving and loading does nothing. I haven't tried atom-smashing the glove yet, but if forbidding it doesn't work, I'm dubious that atom-smashing it would be wise.

To the best of my knowledge, there was never any disruption of her path from the barracks to the glove. I haven't been doing any construction work or digging anywhere near that path.

Interestingly, wagons are unaffected by this bug entirely, and are completely capable of repathing. That might help solve it.

Edit: Also interestingly, locking a door doesn't cause the issue.

In the same fortress linked in my previous note (now running under 0.40.05), Limul Searchedshoot eventually broke out of her catatonic state, but I don't know precisely how. I suspect she eventually became thirsty enough to cancel the stuck job, got a drink, and then started over. She is wearing clothing now.

Since then, many other babies have reached their first birthday, and *every single one* has had this same problem. As soon as they become children, they assign themselves a "Pickup Equipment" job that never gets done. They stand in place until something (thirst?) breaks them out of that job. After that, they are fine.
