Which event we should expect to disappear in the middle of week this time? Asking for a friend.

Would be funny, but unlikely, that event is non-exploitable (unless there is a way to reset daily missions several times per day).

My bet would go to Great Plates. Of course, most of events for keys can be done once per day, but you can draw 10 as long as you have scrolls (and I would guess people have a lot of Bond scrolls), so you could farm keys on that alone.

Because:

1. That would benefit f2p players and you know this game is about anything, but that.

2. They likely didn't fix the bug yet ^^
