Teamed up Valeros and Lem to play through A Fighter's Tale.

Val hit a snag in one of the locations and I had to alt-tab out and restart.

Party (and progress) is gone. 

This is maybe more a feature than a bug, but save the game feature would be nice to have!

Or you did make multible scenarios and the party progress did disappear? Then it sound more like Connection/not logged in the game Center type problem... I supose that this is Steam version? Havent seen this in mobile versions unless that connection problem.

'Fortreit'ing scenario right after party creation helps with party saving.

And characters should be saved regardless of it (on Android version, at least).

It breaks possibility to create a new party with already enabled Permadeath mode though.
