I have a lot of instances of villagers breaking windows and doors. I do have Zombie Awareness mod installed (which has zombies doing this), but wondering if that is conflicting and seeing all villagers as able to do this. I will be checking with the other mod as well, but wanted to point that out, incase others are seeing the same.
(MC 1.16.5)

Is the entity designation for mca villagers different? the mod blacklists minecraft:villager.

I'm fairly certain that this is not an issue on MCA side, maybe report that to Zombie Awareness (if its their feature) or check the config in case there are blacklists.

never mind, got it. mca:male_villager and mca:female_villager. Guessed that the format would be the same as with the spawn eggs. Working properly now.
