I had a wounded hunter who was previously being cared for normally by the dwarves. He had one red injury, which had healed to yellow by the time this problem occured.
The problem, now, is that nobody is caring for him anymore. He's still resting, but he was starving and dehydrated, and -- he just starved to death (for the second time - I reloaded to try some more things to fix it, none of which worked). He hasn't been melancholy or anything like that. He was unhappy due to the fact that he was starving and dehydrated, but he never hit very unhappy and didn't go bonkers.
I had even taken all the jobs except health care away from two dwarves, who sat around with 'No Job' rather than care for the wounded dwarf.
I've 7zipped and uploaded the save file here: http://shadowlord13.googlepages.com/dwarvesStoppedFeedingWateringHunter.7z
Shorast Lokumbavast, whose name is noble pink/purple, is one of the two health care dwarves (the other is Melbil Akrulziril, the Master Mason, who is sleeping).
In between the time that he was being cared for and the time that he wasn't, several notable things had happened:
1. Goblins invaded, killed lots of pets and one dwarf, then most got caught in cage traps, and remaining two fled.
2. We created an underground water source by digging into a murky pool and partially draining it to a level below, and this was set to water source / fishing, though I de-activated it in case that was why he wasn't being cared for. (It is to the south, where the farms are)
3. We had a 'pond' designated for filling with water above the connection between the volcano and our magma room. I de-activated that too in case all the buckets were tied up there. (This is next to the volcano to the northeast, and on the third level from the bottom of the map)
4. While the goblins were here, the dwarves were locked inside, but they were let out again after the goblins fled. For a little while they had no water source, until we got the underground source ready.
I also had carpenters producing buckets as fast as they could once I noticed the hunter was starving and dehydrated.
I also turned off 'all dwarves harvest' to make the health-care dwarves stop picking plants instead of bringing food/water.
The dwarves are also scurrying around with lots of hauling jobs, and failing to load cage traps due to lack of cages, but that shouldn't be affecting the health-care-only dwarves. The hunam caravan wagons claimed to be leaving earlier, but never left the depot - when the goblins arrived, they killed the hunams, so the dwarves are looting their food and such now. They're also moving ore and flux and bars to the smithing room.
P.S. The caravan not leaving is probably not a bug - Trees grew back in their path, so they couldn't find a way off the map. I haven't made a road yet. (I only chopped down trees to make a 5-wide path)
Edit: Also, in that same saved game, you can see a TON of meat and such from the hunams sitting in our food stockpiles, but if you check the Kitchen screen, none of them are listed there. This food was all looted after they got whomped by the goblins.
