You know how to hunt right? Okay if you know, then buff buff to make the game easier? I will answer it,
1. You need to know the many buffs and debuffs provided by LAGS in this game, this game is much better than before that's why there are no cheats in this game because of that.
2. Ghost Hunting, the ghosts that appear and are assigned sometimes do not match those on the screen due to limitations in the number of current maps + relatively many ghosts, look at Mei's house from all the available ghosts as shown on this main page, what ghosts are missing.
3. Regarding the banish ghost ball, I have asked lags about this problem, yes, that bug will be fixed in the next update.
4. It seems you don't yet understand the storyline of each character in the game. How do I explain it? I'm at a loss to explain it, because this game is very complex in terms of story and plot.
