So recently been playing hawk on turn 6 when limbo is active and the game ends.
Same with playing it into deaths domain on turn 6 with other cards to win that location.
Tried it onto bar with no name and it briefly turned in my favour whilst the cards turned but when the game ended it flipped back despite hawk being active.
Not sure if it's a bug or just the way bar with no works.
Anyway for science!
I was watching a Dekkster video and he Hawked Necrosha, which should have lost him the game and then it flipped back and he won. It didn't even flip at the end of the game, it flipped back when his opponent's turn came up. Definitely something fishy going on.
