Ambience cave sounds should not be played as this will confuse the player.
These sounds are not intended to be used in the environments we created.

! We will have to update all these maps to deactivate the cave ambience sounds.

Repro Steps:
Download World of Cars from the store
Create the world (Note: World of Cars has base_game_version set to 1.14)
Wait until you hear the Cave ambience sound while waiting in the spawn lobby.

Observed Results:
Cave ambience sounds are active.
