I just want you to now that we are aware of this and working on it.
As soon as I have new details, I will try reaching out back to you.
Well, just to let you know, many boss encounters are bugged, either not triggering/starting, or trapping player after winning the fight, each time requiring to force exit the area and restart it over from beginning
I too had the Jokul one
I had Bishop of Earth getting stuck in starting dialog (no fight)
I had the giantess in the portal poisonous word not appearing at all at first (getting to the area with 3 light blue circles, and the opened cave blocked by invisible wall, no boss talking)
I had been trapped after freeing the guy in the final room of the Lotnar village
well, i didnt have any boss fight that didnt bug either at start or at end at least once, except maybe the Lady with her two shield maidens.
As much as i like the game so far, such game-breaking issues are really doing harm to the game, as it had an official release and is not supposed to be in dev/early access anymore... Because so far, i feel like i'm beta-testing a potentially good game, not playing it as expected...
I really hope those boss encounters bugs can quickly be spotted and fixed because it ruins the game and i fear it would bring mercyless bad reviews upon a game that would be very fun if not for those...
