What is wrong with Mahjong today?

[Bonkleberry]

Anybody else notice this? I played a game earlier where twice, the game labelled all of my tiles but one with red tiles and the one tile had no marker on it at all, so I played the safe tile and it was a Ron. My friend had it happen to them as well today (they play in the same room as me, so I can see their computer screen). I have never seen this before and it was super fishy.

No, that just happens sometimes, I've had it happen to me playing against the AI. Probably didn't warn you because it would have had to know the player's hand to warn you about that tile, and might only be using information from the discard pile.

It just means it's safe enough. The 100% safe tile in the game is the one that was just discarded.
