So I haven't played this game in awhile, and when I logged in I was riding my horse when all of a sudden this treasure box spawned in front of me. at first I though oh maybe it's for having an account for so long, and these are goodies from the past events. However, something odd happened another box spawned in front of me, and another! I was like wtf is this.

From what I understand, after I googlered it, is that it's from a hacker that's present in the room? what do I do from here?
