Lepers went to a leper colony.
Fairly sure there’s a quest where you attend a funeral.
Check fish traps, if there are no eels they are dead due to overfishing
Finches and larks are in an aviary just beyond the edge of the map. There’s a quest where you have to capture escaped birds anyway, forget what type they are.
There are Jews and jew gates at castles so they’ve stuck with realism there.
As for the nobody aging, how many in-game years have you played?
As for children being unimportant, they would make the game world more interesting, I’ve already converted the point that they shouldn’t be anywhere near the top of the list but a DLC with more realism (children included, but hardly the highlight of the DLC) and more quests, maybe even more in-game area with a larger settlement south of Rattay.
It’s the fact that you look at the game, check the codex and see that the devs have covered beekeeping to special gates for the Jews, but omitted children, when you see that there isn’t even a codex entry about them them and the quest where you have to get the priest back to the settlement east of skalitz talks about the priest having a child then going off to live as a hermit when the mother died in childbirth and you even talk to the family who took the child in, yet the youngest person there is about 16, meaning a church sat empty for sixteen years? It gets quite apparent that it’s actually quite an omission.
