I was playing a scenario with Kyra and Merisiel but got something to do and leave it running, when I came back, the ipad was locked.
I unlocked it and run the game again, its loaded with 2xKyra and 2xMerisiel.
This wasnt a simple UI error, the locations increased to 6 like I really have 4 heroes. I can even play and have differents hands with each of them. Was unable to move any character to another location so, I just pass until run out of time.
When the deck rebuild screen show up, was impossible to select the Kyra and Merisiel's clone to rebalance their decks so now I am stuck unable to progress.
