I hate to disappoint you, but after trying to do my turn for a while, I just gave up in frustration. The game was far too laggy and I didn't know what to do. I even tried to sabotage the fortress just for fun by opening the gates for the goblins, but even then barely anything happened due to the lag. With the seemingly innumerable teeth, heads, corpses, etc. littering the map, doing anything required far too much time. Normally that doesn't bother me in Dwarf Fortress, but this time I could not find any interest due to this not being my fortress. Before this I had never done a succession game, and I did not recognize the importance of creating the fortress myself. This fortress's designs were not mine, it used mechanics I did not understand, and it was being played with a rule I don't use (i.e. no DFhack). I had no irrational attachment to this fortress, so it was uninteresting. I also am just generally not so interested in Dwarf Fortress at the moment, as I normally play the game intensely for a week or two and then lose interest for 6-12 months. That time of interest apparently has passed.
I apologize for the wait and disappointment. I thought I would be interested and complete large projects, but I just can't care anymore. The fortress was irreversibly damaged during my tenure, so I don't have a save file for you, as the fortress was almost destroyed. Just use the last save file uploaded here.
