It seems like the rules are being made up as we go along :(
I can imagine a situation: there's one minute left on the timer, and you need a hero with 2k movement points, but in the tavern, there are 2 dead heroes from tavern level 10+, oh, but there's an autosave!! :D
It won't be a game; you'll just be thinking about how not to break the rules, and this can even happen by chance when the timer is running, which leads to potential exploitation of this issue.
