Sorry, that sounds really negative! Not meant to at all, just disappointing as the game is usually so beautiful, and I'm not sure whether to post a bug or not!
We recently (a few hours before we opened the test) changed over the way we color avatar assets internally. The new system requires going over all the current assets and re-coloring them. We decided not to do it right before the test just in the odd chance it would mess avatars up even worse.
But I guarantee they'll all be fixed and alllllll good before next test or I will eat my non-existent chicken hat.
