Mob loot table broken when updated from 20w45a to 20w46a

When I updated  my world from 20w45a to 20w46a, some mobs like cows,creepers,zombie piglins, hoglins,rabbits and more stopped dropping items and only XP, It seemed to only happen in that world, I tried to re creat the problem in other worlds, but it didn't seem to be the same and it was working fine, I didn't notice anything that big in the world files, so I'm very confused at why is this happening. it has not been fixed in 20w48a aswell
