Sometimes even when I pass a level, at the end of it while tallying the scores, a female voice says "ARRGHHH." Why?

The game shuts down in the end of the first level. I tried rebooting and verified the game's files (integrity of game cache), but the problem still remains. What to do?

I have the cleaner, and as such can't achieve any points on this level at all, since Angela isn't doing the cleaning!

Challenge is 'Only serve one product at a time!' and it still fails in the end, when you do that.

I successfully fulfil the requirements for the challenge, but it keeps considering it failed at the end of the level.
