I've noticed that in a large amount of level sketches the player now appears as a '?'. I'm not aware when this problem was introduced, but there is a solution.
Sorry, this is a bug introduced by moving around some elements internally. It's mapped accordingly in the game, but wasn't for the level sketch images.
Now it's fixed there, too! (As you can see above! :-) )
Thanks for mentioning this problem (that was relatively easy to fix)!
