0003270: Blood has [ROTS] tag, but does not rot
In the raws, BLOOD_TEMPLATE has the [ROTS] tag. No creature that has blood overrides this flag, so all blood should rot and eventually disapear. It does not.
No tags attached.

Blood does not disappear automatically after several years in DF 0.40.23. So (assuming BLOOD_TEMPLATE has the [ROTS] tag) I suppose this is still a bug.

I have looking into this a bit and while I haven't run things long enough to confirm anything beyond reasonable doubt, I'm fairly confidant that milk also doesn't rot.

I think this bug affects everything listed as Extracts. I'll see if I get time to test it a bit more.

Aboveground objects do not actively give off miasma in the typical sense of rotting & remain relatively fresh indefinitely, whilst most stains underground are queued to be cleaned by dwarves at some period of time, but personally i've never seen unreachable blood stains deteriorate underground either.

I do not know, but i would recommend trying a overlapping refuse & dumping zone (as this combination increases degradation) over a blood patch in a locked room underground to establish whether blood even has a deteriorated state to rot into if it is not a oversight.

Needs confirmation for 44. etc onwards, i will edit this space when I can on what i found out.
