At 10th september 2009 the new AA3.0.6 Patch was released, to solve some problems.
The problems with the training were fixed, for example that the game doesn't freeze after starting the training mission.
Also the gameplay was improved, because there were the most of the problems.
Furthermore the statistics were improved. For example the rank display is working correct, now.
Some bugs with the missions were also fixed. One improvement is that the VIP has now the right number of magazines.
The admin-settings were also overworked. Now, the admin-communication-console should work right.
