DP - That has always been the case as far as I'm aware when a new patch is released. You could only play against people with the same version of the game as you, stops any conflicts.

And jaminjack, I have already provided a link to a technical assistance thread for 2048 and HD where SL have acknowledged the issues with 2.40 and have confirmed a fix is on the way in 2.50. They also commented on the videos that were posted detailing the issues. You'd have known that if you'd have bothered to read the rest of the thread.

And I've never been known for talking "horsesh*t" in the 10 years I've been on this site.
