New era.

I re-uploaded the campaign file; this time, the changes affected the second mission: 1) The starting location has been slightly improved. 2) After death, only one Necromancer hero returns to the tavern, and the number of times this can happen is limited. 3) The moment of betrayal now occurs later. 4) The size of the armies stationed in garrisons at key points in the plot has been significantly reduced.
