Here's a patch I've been sleeping on for a while now, because
this thread seemed to indicate that there was perhaps a better fix for this bug, but I disagree. This is the bug that causes the song Spinach Rag to play too loudly in the Opera House lobby when you enter from the outside. I fixed this by simply adding an event trigger to the entrance tile of the lobby that ensures the music is played softly. I think this is an easier fix than Lenophis's suggestion in the thread because it doesn't use any free space. What makes this solution even more elegant is the reason why it uses no free space: in addition to adding an event trigger, it removes one from the entrance to Kefka's Tower that just straight-up shouldn't be there, which can be found about halfway down the opening corridor along Party 3's route, and allows them to grab a hook that is about half a mile away from them.
In other news, my website is getting a massive overhaul because I'm adding a more professional look-and-feel. This includes adding a WHOLE bunch more pages, which is taking a long time, and is still in progress. You can still visit my website if you want, just keep in mind that it's still under construction.
