I had a group, with the paladin, the ranger and the bard. They all had completed until adventure 4-1. About 45 minutes ago, I wanted to play only with the paladin, so i removed the bard and the ranger from the team, pressing, as usual, in the minus sign, near their names. I have done this multiple times, but this time, when i finished the scenary with the paladin and i returned to add the their 2, they weren't there. They have been erased because the program wanted so... And I expect for a solution now.
