hiya i recently decided to start replaying terraria and made a new character and new world, and for the first 4 hours or so everything was normal but suddenly his noise when he gets damaged changed 😭 it was the og sound but now it’s this awful noise suddenly, and i can’t figure out a way to fix it. how do i fix him :( i literally did nothing to change it, it just changed while i was playing??
