by gesturing I raise this topic again.
[sorry in advance for my poor English ^_^]
I have moved in the neighborhood of a tower because I find much FUN with undeads, and at now I am going good with many captive necromancer in the fortress and A LOT of corpses...
but I cannot bury anyone of my deads (few) or necro-dwarves deads (also few but their ghostly presence may be dangerous-FUN leading if they spawn near my dead's pile) because every time I build a coffin and mark it for citizen burial a dwarf corpse
APPEAR inside, nobody carried it.
I have also tried to atom smash every dwarven corpse there were in my corpse stockpile but this thing of "teleporting undead's corpses seeking for eternal rest" is still haunting me.
Now I am engraving lot of memorial slabs and
living with it, I am also massively crafting coffins to test if this behaviour will end after "enough" wasted rocks (test starts with a batch of 200 coffins)... but does anyone knows if there is a way to keep using coffins instead of slabs and leave the zombies to rot?
EDIT: internet left me in the while so I have the results of the "tests"... after 201 buried "dwarf corpse"s I regained the ability to bury other entities. According to the Dead/Missing list there are 201 dwarven corpses deceased so the math is easy.
I tried also to deconstruct and rebuild a couple of coffins, marked one for use after rebuild and the corpse returned there so I left the other one denied and marked for burial a "fresh" one in another room and... the second corpse appeared there too.
I assume there is no way to NOT bury unknown brainless rotting dwarves and now I have a 250 graves graveyard for a fortress capped at 120 dwarves; sounds like "Come with us! Death is common as drinks here!"
