I am on a server which are currently on 1.19.3

I have had a goathorn farm since goat were released (stone floor, 3 height, chickens in boat in each corner with natural logs in front (you can still see chickens).

when goat were released in MC it worked fine, they would try to headbutt the chickens, hit the logs and lose their horns, all the time.

after we updated to 1.19.3 it doesnt work anymore.

its the exact same farm.

I tried to litematica it into my single player 1.19.4 world and it does the exact same thing - no headbutting.

They dont seem to headbutt in the wild either, i just tested in Frozen peaks biome, stood completely still for 3 min with 4 goats running around me  - no headbutt at all

What am i missing?
