I had a region, my first, with a bunch of really screwed up abandoned fortresses. Since I have a second region with which I have been fairly successful, I decided to use the first region to find out what it was like to reclaim a fortress.
As it turned out, the fortress I chose to reclaim had a lake connected to an underground river. It was full of snakemen, lizardmen, olmmen, and as the song goes, "crocodile nasties". I re-abandoned it and reclaimed it about three times before I finally decided that even armed and armored Dwarves were no match for the huge numbers that DF was spawning. Each attempt ended in a tantrum spiral, above and beyond all the combat deaths.
Finally, I used Dwarf Companion to kill off all the stuff in the lake before releasing a new reclaim effort from the initial pause. Everything seemed to go fine for a while, then for no apparent reason everything went to pieces. I tried using Dwarf Companion to try to jolly everyone out of their unhappy moods, and even tried resurrecting some, but eventually it seemed as if Dwarf Companion was no longer affecting anything. I could change things and refresh, and it looked fine, but in the game nothing had changed.
By then there were corpses all over the place that no one could see but me, as well as a lot of gear that had been marked for reclaim but no one would put it in the stockpiles.
I finally dumped it and remade the region from the seed, so I could try some areas fresh.
My questions are:
1. Is reclaiming a fortress more or less doomed to tantrum spirals? I had Dwarves just suddenly flip out while standing in the nice big dining room surrounded by food and booze, and start throwing things.
2. Is there some reason why they ignore some stuff left over from before, even when it is marked to reclaim (or more precisely, unmarked to forbid) and they have some place to put it? They even refused to dump rocks that were marked to dump from a previous reclaimation team. I tried everything on those rocks, and it was as if they could not see them.
3. Is there some reason why Dwarves are irresistably drawn to drink from snakeman infested water on the far side of the map, when they are non-military, the water is marked with a restricted activity zone, and they have a perfectly good well underground?
4. Does Dwarf Companion cause problems sometimes, and stop working other times? In other words, did I cause a lot of my problems by trying to use DC to save the fortress? I don't normally use it, but it seemed like a good thing to try with so much going wrong.
5. What does Tweak change? Is it only in memory, or does it change files? I was experimenting with it just before I gave up completely on my reclaim efforts, just to see what it did, and I couldn't see anything happening. I don't mind that. I just want to know if it changes any data files associated with the game.
