Well the next cup round has not had that long of a delay. I can't remember when I had to wait training for this long. We all do have a game tomorrow. Training is a pretty vital knowledge, because of game shape. Depenging on it you choose the starting lineup and consider effort depending on your opponents game shape...
The standing update has always been a bit "unstable", so this is not a problem any more :)
I do think the little additions that create site bugginess are not really good for the game. The season start is the most vital time of for new players to join/decide their dedication to the game. If it's buggy, it's easy to quit...
Perhaps try adding the new things in the middle of the season, when there are not as much of the other processing going on? Having a down time for offseason processing and stuff is not the solution. You might check all in the downtime, but the bugs appear when people are using the program. So you can't predict the bugs before you actually see them.
