No.03721 Fujix Administrator Feb 4, 2009, 08:34	Probably it is an original bug. At any rate, we need a save state or something to help reproducing the issue.

No.22272 izius Tester Aug 19, 2024, 20:02	I was able to reproduce it on the player side. The game recognizes that tile pattern (sequences of 123, 456 and 789 in 3 different suits) as Sanshoku Tsuukan, a local yaku worth 2 han (1 if open) (see the attached screenshots). Implementing local yakus is an odd programming choice but, by the game logic, the reported hand is valid.
