Did someone forget to tell you guys this was a BETA SERVER?
It is expected to reveal problems, and you're supposed to accept it.
If you don't want bugs... don't join a BETA!
Do not confuse the term beta with beta test. Is not the same. In beta test if you risk changing everything every 5 min or every day, and even to close the server without prior notice. But A beta where you can (and you have to do it if you want to play in normal conditions) spend your own money in addition to your time. It is not a test. And it is. Well, it should be free and equal.
