I have been playing the open beta since yesterday and have found the following bugs:
* Somehow after the server disconnected in the evening I have an issue with changing from Ground battle to Space Battle and reverse. When changing battles (be it from space->ground or ground->space) my character reappears incorrect. When I am changing to ground for example, I see my ship as my character instead of my male vulcan. Otherway is the same, when going into space again I have my male vulcan character instead of my ship.
This sometimes resolves itself after I am being haled or get more info about a mission but its very annoying.
* The first time I went in to the VEGA system it hangs on the loading screen. I have read that there are performance issues with the VEGA system but I am not sure if this is related to it or not.
