"enttiy.zombie.infect": {
"category": "hostile",
"sounds": [
"mob/zombie/infect"
I think it should be:
"entity.zombie.infect": {
"category": "hostile",
"sounds": [
"mob/zombie/infect"
The "entity" word I think is wrongly typed. My proof is in MC-91102's sounds.json file after the entity.zombie_pig sounds.
And it still worked! ;D
2 other places had the same typo ftw😃
