Lighthouse boss fight softlock

[Chaotic Fear]

So I got to the Lighthouse, fought the first boss and beat her. Then I got to the second part with the two bosses. I'm guessing because I managed to push the boss with the wrecking ball off the level to her death, then going after the bow and arrow boss, that same boss is now standing behind the door and won't trigger the cutscene to the next part.

Tried to quit the game and come back, but to no avail. I hope there is a way to combat this or hope this gets fixed in the future.

Edit: With the quaduple jump available, I managed to get to the next platform you're *actually* not supposed to reach. Still could not interact with the bow and arrow boss. I went to the top and triggered the third boss and finally all three of them together. However, the bow and arrow boss pretty much left right after the cutscene and I fought only two of them. Once defeated, the door wouldn't open and am now stuck once more.

Just ran into this same bug. Pushed one of the bosses off the edge on the second fight, killed the other, and then... nothing. No boss comes back, no doors open, just stuck.
