played a game with one other kingdom and four challenging empires against a custom sov & race, at end of game my power rating was 3840 the last empire was magnar with 20 and tarth was 219. was researching the economy boost +10% EACH turn, (all non-repeatable research was completed),magnar decided to attack one of my smaller armies that was surrounding him (that had three of my fast heavy horse archer companies armed with ignys bows and fire attack  accessories (i also had 20 fire shards)( the last magnar army had 7 units including the sov and three heros, the other three were 3 member squads) when magnar attacked my army I chose to fight the battle, during the battle I killed all of the magnar army and at end of turn the research window opened and would not let me click on done to close it (I did have all available treaties with tarth).

attached a rar containing the saves AND the debug.err

the only way I could end the game was to  end the program via task manager
