This has happened twice now on this tournament. I used gold for an ultimate twice and both times a rollback immediately fired and set the tournament back 2 rounds. Conveniently the gold that was used for the ultimate does not get put back.
This has to stop. It's blatant theft of player resources. You will notice that some things get rolled back appropriately when these rollbacks happen but things that are more important to the player do not. I also lost the ad views that I used to speed up being able to battle.
I've already submitted a ticket. I've submitted several tickets in the past for the same issues.
