I bought the challenge pack, and level 49's unbeatable?

[Guest poppy]

I kinda said it in the topic title, but level 49 doesn't seem beatable at all, as soon as the level starts, the 3 enemies fall onto the boulders, drop dead for some reason, and the door doesn't open...so its just 3 pushable boulders and no enemies, so I can't get anywhere...Am I missing something? I don't see anything about this anywhere on the internet. ;

I have know idea I never got that far.
