I have my villager farm that works almost perfectly.
Two main issues are
Villagers drowning on the water elevator
Villagers not walking over the trapdoors
Here are screenshots of the way this works.
The idea is very simple, the little villagers can walk on the open trapdoors and fall down into the riverflow which leads them to the water elevator and they get out in a separate building.
The big villagers cant walk over the trapdoors since they have only 1 block open.
But the villagers dont walk out, even after a few hours they either go into the water and drown or they dont fall at all, they just stay there.
When they reach the escalator the little ones are just sitting in the water on the half-slab and start to drown SOMETIMES. Probably about half of them make it safely.
An old design for a villager farm that I used only had 2 trapdoors and it was almost 99% clog-proof. This one has probably more than 30 and its not working...
I have tried to place the trapdoors against the outside wall but that didnt change anything.
How can I improve the design of this villager farm ?
