I had a self drawn mixed shifted chows which is 6 + pung of terminals which is 1 + self drawn is another 1 for 8 points and it did not declare me as a winner.
Also, flowers are disabled maybe that's temporary but flowers are part of MCR. They are worth 1 point each and can be used as a safe discard. They can automatically be declared for a point or kept in hand to be used to discard safely.
