I came back to edit, but my review is gone. My puzzle pieces were gone from inventory and I couldn't collect any more to upgrade the new single building uptade. I submitted 2 service tickets and all responses were the standard copy/paste responses. My account was eventually fixed without a response from devs. Support is like chatting with a street sign. Now there is a builder bug. Yes, again I submitted a ticket. And below you will see another copy/paste response from support.
