When some villagers are too close to bushes or wood (never experience this with gold or stone) and the place where they drop the resource accordingly they get stuck between one and the other, I have to manually move them to make them work again however they do not show as idle villagers, however after certain time they actually fix themselves.
Reproduction Steps:
Start any match multiplayer or not
Build a lumber camp or a mill with 0 tiles distance between the wanted resource
I played several games and for me it’s pretty much fixed. Still having issues but much rarely (like had 15 times more villagers stuck/game in the previous update).
