Why couldn't this hand win with ron?
Occasionally, I try to Ron, but get prompted that I cannot due to a "missing multiplier". What does this mean, and how can I avoid it?
Example: The marked tile was just discarded, but I can't Ron.
Edit: A quick explanation why this question is on-topic on this site instead of at gaming.stackexchange.com.
The exact term "no multiplier" is certainly specific to this implementation, but I believe the question applies to the game in general. This message does not appear to be a "bug" or "error message" but a valid notification that my hand is missing something. Maybe (I'm guessing here) it should just read "Your hand does not have enough yaku yet!" instead.
