Alpha Patch 2.1.2 has been released to Live, and is now available for players! This patch is a very targeted bug fix patch for Crusader and Arena Commander.
Your launcher should show "2.1.2-315233" as the client version. It is strongly recommended that players delete their USER folder for the Public client after patching, particularly if you start encountering any odd character graphical issues or crash on loading. The USER folder can be found (in default installations) at C:\Program Files\Cloud Imperium Games\StarCitizen\Public.
Please review our list of 2.1.2 
Some important call-outs:
- A jet-pack looking item has re-appeared on the back of characters in Crusader, that will occasionally flicker in or out of reality.
- We are aware that ArcCorp is still suffering from some texture problems and level of detail popping.
Arena Commander Module

Persistent Universe
Fixes
Environment
- Made several changes to potentially resolve the extreme audio corruption that could be experienced during extended gameplay sessions.
