During a play, while I was browsing support portal, my castle of level 73 was switched with level 1 ( tutorial going on). I've logged out and logged in several times, still I could not reach my castle. My profile with level 21 and all friends were the same, but all else was reset to beginning. How can I restore my castle?

What a relief. I've found it. It seems I accidentally switched form untamed to dark plains, but I found the option in my profile panel. :)
