Blooner, my 1,87Mb mission with 2 ogg files won't work. Yet 1,2Mb mission without them do.

Look like we had bad luck there, we've done our tests with 150kb file.
EDIT:
I got my mission down to 1,87mb and it still wont work.

Same issue. +1 up

While I don't believe in copyright conspiracy I can confirm all the findings. You might want to look a little more into single file size, but apart from that we successfully reproduced both outcomes.
