Currently, it’s held in the basement of Forsaken Abbey, but it is better to change it to a dedicated personal instance that imitates the basement of Abbey. There are two benefits.
1. If one player (A) is already running "Rescue the Musical Angel" in the basement of Abbey and another player (B) warps from Nedo Andus to the basement, A bug that (A)'s running event game is interrupted occurs.
This can be prevented by making it an individual instance.
(I suffered from this just a while ago.)
2. While playing the event game, player can prevent behavior that is an act of sabotage by an insensitive and thoughtless childish player from appearing and opening the automatic door to enter the basement of the Abbey without hesitation.
(Opening that door is a obstacle to the movement of the player during the event game. It is insane. )
In terms of time, Music Festival is nearing its end, so if it's realized (no, I think it's absolutely essential), it's likely to be next year (although it should be done immediately, if possible), for the time being, I suggest this.
