I've had a pretty awesome fort going for a while now. I'm able to turn back pretty much anything that comes to call. The problem is when an enemy gets in a lucky shot, or when one of my non-military dwarves is on the surface cleaning up the mess that WAS a goblin siege when an ambush arises. Since I decided to make a legendary dining hall with gem window walls, and a masterwork adamantine statue hall all my dwarves started being FRIENDS with one another. So much that now everyone in my fort has almost legendary social skills. So much that when one dwarf dies, 90% of my dwarves get major unhappy thoughts. Combined with the miasma that arises when there are just too many pieces of goblin to remove in a timely manner, it's enough to bring my entire fort to the brink of a tantrum spiral. Given that if I DON'T pick up the goblin splatter after a battle I get plagued with a progressively degrading framerate, leaving it out there isn't an option. Indeed, just leaving their equipment out there causes a pretty bad frame rate hit. But picking it up puts me at risk for a second attack, and I can't afford another dwarf to die. I'm seemingly at an impasse and don't really know what to do about it.
edit: once I sent a suicide squad to deal with a forgotten beast with instant necrosis vapor breath... a riot started almost immediately, since the corpses began rotting instantly. Thankfully my game crashed, and I got the chance to do some things differently.
