@Inetsky: rotation only becomes available after the third level for a process. So keep updating until you see those two circled arrows (refresh icon) next to the piece.
I can't reboot anymore, it says access denied. Although I researched it a long time ago. Lots of things are wrong after the update, so I thought rebooting would be good to start over.
"We may need to do this a few more times in the future". Why would people keep playing if you're probably going to reset their saves again? This game has so many (small and bigger) bugs it shouldn't have been released yet to public.
