There’s actually 2 bugs on the music:
If you start the game and end it quickly, the music is still there. It’s actually a great bug if you want music on the lobby. (it sometimes won’t work)
PROBLEM:
The music bug happening in the lobby from the 1st one won’t restart. Just the same song will happen, and imagine hearing this:
Your normal music:
dun dun dun, yes yes bam, uh huh, rap, yes
The bugged version:
dun dun dun dun dun dun yes yes yes yes uh huh uh huh rap rap yes yes
Imagine 2 of them mixed up. Not that good.
The only way you can get rid of this bug is to close out your map and open it again.
