Breachstone music stops halfway through map. Restarts after boss kill

Hi, the breachstone background music stops halfway through the map. I think it doesn't loop. Music starts again after you kill the boss

This happened in both esh, xoph and tul. Haven't checked the others

Confirmed in chat that someone else has the same issue

bug 2.266.445.903

Confirmed in chayula as well

Extra info: after "restarting" on boss kill, when you rejoin the monsters' area the music plays once and ends abruptly at the end, not looping again. Of course you should be out of the map by then but still
