When every I use it. It never swaps all. And to break it down before people say lv need to be the same what I'm talking about is the Hogyoku and Soul don't swap. Yes it shows it does til you refresh. The the map and hogyoku are back to the person you swapped from. So if you swap right before the event you think your ready but you don't do the damage you should. And don't know why til you refresh. Can yous fix this already!
Not sure about the Souls I think they do swap but the Hogyoku sure do not. You can see your BP drop but when you go into the embedding you see they are there. Refreshing will show that they have not swapped and you need to do it manually
