now I'm playing 0.47, since that's where all my mods are, anyway, dealing with bone fractures and I came across a problem patient.
They had an overlapping fracture of the ankle, and some other fractures, after an encounter with a necromancer antman queen (note: any creature that is strong enough and has enough arms to carry 3 shields is extremely good at blocking).
So, when they were recovered to the hospital, the doctors came in, diagnosed them, scheduled treatment and.... treatment did not progress. Every time, a bone doctor would appear with the "set bone" task, but they wouldn't set the bone on any of the wounds, and they left the task uncompleted, then another diagnosis check happened, and it was an endless loop, with the fractures going unset, and undressed as well.
Checked with other patients with broken bones, and they were treated alright.
Used dfHack to teleport the patient up into the air to reinjure them, and while this caused some more fractures in different parts of the body, the same endless loop kept happening.
After about a year of this non-treatment, I used dfHack's gui/gm-editor to remove the "overlapping" flag on the broken ankle wound, and this change resulted in the bone doctors setting all the broken bones, dressing them, putting plaster casts on, and finally releasing the patient from hospital.
So there seems to be some problem with overlapping fractures (at least when there are other fractures, not seen yet if the problem occurs in isolation).
Does this issue persist in the latest version ?
