I am having issues where I cannot keep the mute on in The Bandit Dungeon. Every battle it un-mutes itself and when I look at the icon it says it's muted. I have to un-mute it then mute it to stop the music for the 1 minute that the battle lasts when I am grinding then do it all over again.

I reloaded the page several times.
I have restarted my browser.
I have switched browsers chrome to firefox.
I have hard reset, which reset my entire dungeon despite having already DONE that once today.
Also shut my entire laptop down and booted everything fresh.
