Seems the size of the pieces in the tray are vastly different than they are in th puzzle. I find that very annoying.
This is an unfortunate bug, that causes this. It will be fixed in a few days time, and the pieces will be a fixed size in the tray, not different sizes. Please see this article for more information:
I don't think the bug has been fixed as was indicated. Is there an update I'm missing other than the last one sent. Thanks
