What you were expecting to happen
Units cannot appear twice on PvP defense team, right?
How often does this happen? When did it happen?
I started PvP Arena. And suddenly, I realized that the ennemy team had two King Gobtruffle! I don’t know if it was made possible on purpose…
Steps to make it happen again
I don’t even know how it is possible! I’m really confused right now.
I don’t know if I can make it happen again
I dont know why you think you can not use multiple troops in a PvP defense. The only time you wouldn’t want to is in Guild Wars and that is just for the purpose of extra points.
