Hi,
I think the idea to go back to closed alpha is not helping at all...
The biggest change to go from alpha to beta is to increase the number of players... no idea how many there were in the alpha but the beta had ~9000 players on the weekend... so this number puts the servers under stress which in turn might reflect strange behaviour of the game. And this might be EXACTLY the thing the devs want and need to see, so they can improve their soft and maybe hardware to correct for these errors.
So keep on testing, remember this is still beta and bugs will be there and need to be reported... so instead of writing posts about how buggy the game is, better go to the "report bug" page and do your part as tester ;)
Volle Kraft voraus, Herr Kaleu!!!!!
