100% the correct file.
The reason why the FB is in the hospital is because the bridge is at z22, and the hospital is at z80. So either there is a second bridge (which is currently raised) or second hospital or someone's made a bit of an error here. In hindsight, the best move would have been to make a second hospital rather than retake the first hospital.
I've played for a season, which is partly what the issue is. For a lot of the deaths have not been dealt with from engraving slabs/burial because every single coffin is full. I suspect if you play for an entire season you'll notice it takes a while for the slabs to be done and my guess is that you'll find a ghost in this period.
Booze was at "30" not 0, but it's close enough to 0 considering the size of the fort.
To be fair, i don't think any of the problems are particularly difficult. I shall reseal the caverns and take the hospital back at a later stage.
It's just with the military as it is dealing with a FB is rather beyond hope, but in 2 years i can probably sort it out.
Someone else will need to resolve the marksdwarf situation. Not my speciality, i couldn't even find where they train, unless they simply train on goblins (i've had success with archery targets a way back, not used them in years though).
I shall relocate the hospital and cancel the one at z80, as it makes no sense anyway, if there's 2 bridges, it makes more sense having the hospital inside both bridge defenses.
edit: just found the second bridge. Why you would put a lever on the ground level to deal with the caverns next to one for outside...
Lets put it this way, i don't remember which is which, it's fine anyway, damage is done.
Also, the FB can get in anyway, the 3 cage traps placed to prevent the second entrance is terrible, i'm unsure if you put it there, or what.
I.e, this area here, is where anything can simply bypass your bridge and wander straight up into the fort, except from the bridge at z22:
Might be easiest setting up a second bridge to block there also. I suspect the doctor wanted to get into the caverns for something and seeing it was unclear how to get past the bridge in the caverns, he just made a second entrance. Will probably have to deal with that sooner rather than later.
for a fortress which doesn't use the caverns, there is a LOT of corpses of troglodytes and crundles in the caverns. Which seems to confirm my theory the good doctor had some fun down there.
From the military perspective: I will AVOID use of melee combat, but will make it possible that melee combat can be used with high skilled fighters to deal with threats such as the FB in the hospital. Seeing that's an area i can deal with.
As it is, i will seal off the fort at z22 until i'm at a stage where i can use melee to retake any other levels. I have placed a lever which deals with the bridge at Z22 at Z21. There's enough confusion on the surface with just 3 levers anyway.
