No mods, but I do use DFHack and Quietust's binary patch to prevent military training rage.

Also in this save, I have not received migrants for many years (no message regarding them either) nor have I had any new births in a similar amount of time. I would open another issue for that, however, since the save crashes after a few seconds, I think it would not be very useful for troubleshooting.

 Tried the save. The crash is in the squad code related to schedules. I notice that one of your squads (the one with an unfilled position) has corrupted correspondence between positions really occupied by units, and the ones they think they occupy; specifically, the commander thinks he is in position 5 instead of 0; position 8 thinks he is 7, and 9 thinks he is 8. Did you by any chance use any hacks to assign units to positions, e.g. maybe Dwarf Therapist?

As to migrants, having about 3000 units on your map (dead or not) stops them completely. You have 6000+. The fix/dead-units script from dfhack cleans out uninteresting dead units from the unit list, and it was reported that it helps with migrants too. Disclaimer: use at your own risk, etc.

Edit: And sure enough, fixing those position links enabled it to run at least for 1.5 in-game month without any problems.

Since you are using dfhack, here is a tested script to fix the corruption:

for _,squad in ipairs(df.global.world.squads.all) do
  for pos_idx,pos in ipairs(squad.positions) do
    local hfig = df.historical_figure.find(pos.occupant)
    if hfig then
      local unit = df.unit.find(hfig.unit_id)
      if unit then
        unit.military.squad_position = pos_idx
      end
    end
  end
end

Yep, I did use Dwarf Therapist to assign dwarves to squads. Good to know that is a little buggy, and thank you for the script, I'll give it a try. I guess this can be closed out as it is not a problem with DF itself.

Thanks to you both for investigating and reporting back.
