Siege battles start automatically in "Auto" mode and therefore making Hegemon attack immediately as it loads, if he successfully 1shots the whole enemy team then the battle lasted Zero seconds and errors out saying: "An error occurred due to invalid battle duration".  [ClientLogicException "l":Battle_InvalidClientDuration "f":True].

The error forces me to restart the game and I end up losing an Attack Scroll even though the fight did not Register as a Loss or a Win... 

Also, because of this error, even though the battle did not register as either a Win or Loss, i still lose access to my champions in Siege as if i already used them.

Possible fixes:

1. Make Siege battles start Manual instead of Auto by Default.

or

2. Give fights a 1second Delay after loading, before Hegemon attacks with his A2.
