It's a bug, problem. I've crashed and had it happen, you just have to keep retrying til it works. It's only happened to me once with the constant relog attempts, the other time I got in right away. Like they say though, it's just a beta but it seems if things go well enough they're going to update a lot of things.
Random guy I ran some Vaults with in game told me "friend of a friend" that works at Turbine said they may be doing a quest overhaul, etc. to really update the game. Whether all the things he told me were true or not, not sure but if they are it'd be all the more awesome.
Yeah, just the one server but there are always PvP zones and PvP flags we can run on. I remember using Bash back in '02 and knocking kids like 500 yards and killing them, hopefully I can still launch people up hills.
The game is a lot tougher than I remember, just due to the need to group for all the Vaults and the inability to land a lot of hits. I'm 16 on my Defender now with 10 Melee Grandmaster and only around 67% hit chance, lol. With 15 Heal/Vigor Restore, but things are getting a bit smoother and maybe they'll give us an animation update.
