From Alliance Games website:
Because of a server crashing bug caused by the Wizard Eye, we've had to release a patch to version 2.1. Players and server ops alike will need this patch so please head to our downloads page and grab it. I haven't had time to update the full versions yet so if you're downloading alliance 2 for the first time, grab the full 2.0 as well as the 2.1 patch.
We suggest that server ops may wish to have autodownloads enabled to allow clients who have not yet upgraded to get the small patch.
• This patch fixes a major server crash bug with the Wizard Eye. It also fixes an auto switch weapons bug with the Minigun and turns weapons announcements off by default.
• Quake 3: Arena
• 1.27g beta patch
• Alliance 2.0 mod
