Bug in the last level of the ice planet

Hello and thank you for this truly great game. I discovered a bug in level 8 of the Ice Planet: It's not possible to rotate the line "ADAM HAS YETI" using the four magnets, as the rotation is always out of sync and only produces the line "ADAM HAS YETI" but never the line "YETI HAS ADAM." I think this is due to the order in which the four directions are checked.
