I keep getting deaths in the danger room that doubles as fort meeting area. The first one was a few years after I started - a dwarf fell onto the stone floor of the pool and smashed his throat. I savescummed that because it was never supposed to happen. It happened again a few years later, and that time I accepted the loss as inevitable, although I did replace the stone floor with wood to try to prevent more deaths. Now two more have died - one apparently the same way and another from (it would seem) actual blows from the wooden training spears. It's really getting annoying, since there's no other good way to prevent lots of fort deaths from other things (such as forgotten beast attacks and goblins). Maybe I should be going with one spear per tile instead of five, but the child care thread produced good results (and relatively few deaths) from five per tile, especially once Staalo replaced the stone floors with willow ones.
I savescummed the last two deaths, mostly because I couldn't find combat reports and thus don't know what went wrong. If I did, I could write off the deaths as hard lessons learned, but this way it's just pointless.
Moreover, not much happens in the fort year to year. Losing a year or two doesn't make much difference. I will have to re-order the steel armor I made for my eight hammerdwarves and re-butcher the giant moth. But that's about it...
*sigh* This really gets me down, not knowing why.
