This patch should be reasonably stable (famous last words!) as I have been playing my test campaign for quite a while. However, there are always some issues with any new release so don't start any major campaigns for a week or two until any obvious problems are found and fixed.This is a database patch so if you upgrade you will lose your saved game. Don't upgrade if you want to keep playing the same campaign.This patch can only be applied to version 4.2 or later. To apply the patch, unzip the patch file and copy the files as follow:1) Stevefire.mdb and Aurora.exe into the installation directory, overwriting the existing files with the same names2) a11.jpg, b20.jpg and M24.jpg into the Planetjpeg sub-directory (if you don't already have them)3) flag0390.jpg and flag0391.jpg into the Flags sub-directory (if you don't already have them) http://www.pentarch.org/steve/Aurora640.zip (12Mb)Patch notes are at: http://aurora2.pentarch.org/index.php/topic,6532.0.html This database in this patch contains my current single-player Aurora campaign as an example game. This is quite a large game so if you start a new campaign, its probably best to delete the example game.NOTE: As of 19:30 GMT on April 23rd, this patch includes the v6.41 updateSteve
