The npc mob now makes a villager sound, this only started when the 1.17.30 update came out, also when you have an item in you hotbar and you select the item it will now no longer display the iten above your hotbar.

The npc mob no longer shows its name text above its head forever, now you have to look at the npc for the name to pop up, please fix this bug fast it breaks alot of my maps.
