It's a strange thing: the game crashed, but it didn't close – we're still playing, and everything seems to be fine... no crash log was generated (or I can't find it, I've searched all the folders)... what was that?
P.S. At the same time, the TeamViewer session was interrupted. It seems to be related to the connection somehow.
P.P.S. And now the game seems to be stuck during the pink player's turn... (no, not stuck, the opponent says he's making his move. maybe it's some kind of desynchronization)... it's back to normal.
