here is the bell
there we go, one without optifine in 1.16.2 with the f3 debug screen enabled. Sorry for being a pain lol.
I affected the villagers with glowing so you can see where they are during meeting period (time set 1000) and the lime concrete represents where the bell is.
my bad let me get one without optifine
I just checked and they still just stay in their houses and chat rather than going to the bell
