Why Yakuman Chance?
Only 9 sou dora indicator, declared riichi and had yakuman chance for another 9 sou, I can't figure out what the yakuman was. I mean, it would have been a counted yakuman, but from what?

How does scoring actually work? In the scoring on the mahjong academy tab, a child haneman should be 12000 points, so why was this one only 9000? I've also had parent mangan with only 8000 points, when the table says it should be 12000 points.
I haven't seen it explained anywhere (I'm sorry if it has, I just haven't seen it), I also haven't been playing mahjong for a long time (barely a few months) so thank you in advance.
doesnt matter if i try the app, the web version on my phone or on my computer, no tweet is sending specifically from my main account (i can tweet from other accounts), though i can still retweet/message others perfectly fine
does anyone have any idea why?
