Bug: I lost all active heroes. Few minutes ago I couldn't Edit heroe on Heroes screeen (no data loaded) so I returned to the main menu and refreshed the webpage. Version has been changed from 1.1.3 to 1.1.6 and my active heroes disappeared (along with equipped items). Those that were not assigned to the formation are fine. Unfortunatelly most of the progress is lost.

It's got fixed, thanks for the report.
