Not to hijack, but I'm not getting a jump bug from mahjongg. I have sims sit there, start moving the tiles around, and just stay sitting there motionless for hours. Even when there's only four sims on the lot and everyone's at the table (so they can't be waiting for another player). No errors are popping.
Not to contribute to the thread hijacking, but I've been having the same problem with the poker tables since BV. Four sims will sit down to play, but never get around to the actual playing. I don't use the tables that often though, so I haven't really dug down into trying to figure out what the problem is. Haven't even tried the mahjong tables yet.
