I reported this bug to support but they still have not fixed this. So I am going to share this HUGE bug with the community so hopefully this will gain some traction.
This is only possible (as far as I know) when you Menhir your village.
It's very easy to duplicate.
So what you do is name your village "000"
OK this is probably the hardest part: You must find someone to send you a Menhir invite
And then when you Menhir - your village name will become "0"
This is only 1 character long. The minimum character count is usually 3.
So congratulations, you just circumvented the minimum character count.
Please don't abuse this bug.
