I am not sure whether the problem that caused me to reach this game state has been fixed (I have not played since it happened except to check whether the problem with my characters being stuck was fixed after each update), but I am still stuck in the victory screen when I load the game, both via 'continue' and via 'story'->the play button on the party in the party selection screen. When I do that, the victory message appears, followed by the gold reward being shown, then after I press continue on the gold reward box it proveeds to the victory character rewards screen where both of my characters are dead and the triangular continue button is not lit and does not do anything. I think the problem is that the game does not let you continue until someone has received the rewards for victory, but both characters are dead and ineligible to receive rewards, so the game is stuck waiting for the rewards to be delivered to someone but there is nobody able to receive them.
Normally when victory is achieved at least one character is supposed to be alive still so this would not be an issue, but due to the bug mentioned above I reached the victory state with no living characters and the app does not have a way to handle that.
As a side note, I am worried that if/when the problem gets fixed, the scenario will be counted as completed which will mess up the ability of my characters to receive their rewards from it when they complete it for real.
