Has this ever happened to you?
My buddy and I were playing DE last night, and we got to Grimrose. We killed the center blossom, and we each took a lower corner and shot at the side blossoms.
Then, we killed the remaining two blossoms at the exact same time...but then, nothing happened! The boss music kept on playing, no crystals appeared, and those stupid Dull Pixies kept bouncing around the room at high speed.
We ended up having to reset, but at least we weren't that far in the game.
It's worth pointing out that I've played this game (both alone and with friends) about 45,000 times, so I know this isn't supposed to happen, and that I didn't just miss something.
But yeah. Anybody?
