Medium/large-sized slimes and magma cubes don't have jumping/landing sounds

Xperia Z5

Slimes and magma cubes don't make sound when they move/jump. The only sound they make is when they get hit.

EDIT by Zeb: This bug occurs with all slimes/magma cubes except the smallest sizes. The smallest slimes & magma cubes both have their proper jumping/landing sounds.
