Wouldn't say this is exactly inside the game but upon opening the data,win of the game on UTMT it prompts you this pop up and lets you proceed without you being able to check on any assets
Noticed when i updated my games to the v1.0.1 AND v1.0.2 versions they both had some sort of bitcrushing in most audio clips besides the music, i do not recall the sound effects sounding like this in the sendoff release version.
