This just started happening, and I have no idea why. I have a battle processing events and now for some reason the battle bgm won't end when the event ends. I don't have anything in the troops tab to change the bgm btw. I just use the system default "Battle 1" right now. Below is the event. I have it set to erase event so that it Disappears when you defeat it, but will "respawn" if you leave the area and come back. View attachment 92196

Edit: I started a new game and it was still screwed up. But then I exited the entire RPG maker software, re-opened it and the problem was gone when i created a second new game. So, idk I guess it was just some sort of bug.

Edit 2: Ok so I figured out what is causing it, but not how to fix it. When I interact with an event, which starts a quest. (pictures below) It happens, but if I don't start the quest it's fine. I don't know if it's Colos himself that causes the bug, or maybe the switch, "Colos Quest Started" that causes it." The 5th tab was empty with the condition if self switch C is on, not sure why it was there, since there was nothing to turn the switch on. So I deleted it so there is only the 4 event pages below.
The "No color" switch is turned on at the start of the game, and is turned off after a certain point, in which I don't want the quest to be available anymore, which is why the first page is blank.

Edit 3: I copied the event and edited a portion, tested it, rinse and repeat, and I found that added Colos to your party is what triggers it. Not anything to do with the "Colos Quest Switch."

Edit 4: I GOT IT, ok so when I added colos to the party he wasn't initialized. Although I'm not sure as to why this would affect the battle bgm. And it raises another question: What happens if I want a character to leave the party and them come back with all of his levels in tact? Will the same thing happen with the bgm?

Edit 5: Wow this has become a huge wall of text, but once I added the colos quest switch back into the event, it happened again. After going through another testing process I'm sure that adding the actor is the problem, ( I know this because I created an event that just adds colos to the party) but there isn't anything abnormal about him so I don't know why it would have this strange effect.

Edit 6: Ok, so I decided to see if colos was the problem by creating an event that adds a different actor the party, I used the default "Brenda" and it happened. I tried it again this time adding "Natalie" also, with identical results. So for some reason the glitch occurs when there are two or more people in the party.
