Well, actually i save 2 of them (another one was quite strong, and now basically unbreakable). And the 2 of them are in the same situation
1)Make sure that your doctors with diagnoses enabled have some spare time (it doesn't have to be the CMD, just any doctor with the diagnose labor).
Not a bad idea, but my doctor is currently doing nothing, and has already come to diagnose the OTHER dwarf and then came back to do nothing elsewhere.
And, moreover it's not only a problem of diagnosis, nobody came to give them water or food either.
2)Try mass enabling the diagnosis labor on all of your dwarves. Somebody is bound to notice him and help him and even if they don't do a good job they will open up the way for a real doctor to come in and do a good one.
Could be a good idea, but it's not only an issue of diagnosis but also food/water (even if, it's true that they are not thirsty yet). I will try later. But the fact that when the other dwarf (my militia capitain) was injuried, he was immediatly taken care about, fed given water and fixed made me think that there was a real problem.
3)Check to see if he is actually still injured. If a dwarf heals fast enough it is possible that they heal before they get all of the way to the hospital, leading to them trying to "rest" but the doctors never diagnosing them because they aren't hurt. If this is the case try destroying the bed out from underneath him and see if that does the trick.
Heavy bleeding (for one of them) + leg broken. And yes, "Diagnosis request" in the health tab.
4)Worst comes to worst you can re-injure him and your doctors will probably notice him. This can be done by setting up a cave-in directly next to the bed, though you will want to ensure that the level beneath the cave-in area has a solid wall to stop it from plunging through the floor.
Perhaps i should do that...
And the "remove bed", i have already done that. And....somebody took him to another bed of the hospital. Which make me think that they are viewed as injuried.
