I suggest a very simple solution for the organizer to get out of this incredibly stupid situation: Alexey, allow leaving as many heroes as you want on the map, and use the strongest of them to determine the parameters (because this is a secondary criterion). Or, set a condition - only Gem remains, and she MUST perform the last action.
PS The second option is almost impossible now!
The sum of the parameters is calculated ONLY for GEM!!!! This immediately eliminates ALL disputes about stuck heroes, etc.
Sincerely!!
