This has got to stop.

When you announce, on a server, that you are going to shut down a server at a specific time, then shut it down at that time.

We are getting tired of seeing announcements saying " The server will shut down at 0500" planning things out ( in this case, research that would have been done before that time so that new research could be started) only to have the server actually shut down at 0443.

Get your act together. You are pushing the people who play your game to the point where a lot of people are ready to tell you where to shove it, and quit.
