well actually i did battle him

i was doing the dungeon solo and got to the final battle where i was defeated (by the way i like how you made it like a chess board and how you used the little known chess move en passant)

anyway after the battle i logged off only to come back 2 days later with the quest helper telling me to go to avery and now he's congratulating me on something i didnt do and now i know the ending i wanted as a reward for my hard work but got it anyway without having to do much and now i'm sad...

my concern is for the players who like working for stuff to feel that sense of accomplishment who may end up in the same situation plz fix it

What's happening is the main quest goal for "The Final Countdown" changes to Talk to Avery after we defeat the Machine. It shouldn't change until we defeat Kane's court.

That, or the battle with Kane is optional?

I am fairly certain I saw One Eyed Jack indicate this was a bug to be fixed soon.
