The bug is just what the title says. I spawned under the world in Area A5 (I believe) on the Hydra's Den server, so I was immediately killed, and had to spawn again, only to have the same thing happen about 7-8 times in a row. This is frustrating, but I know it's alpha, so hopefully it will be fixed soon.
That is outstanding! They'll get it fixed man. Patches are flyin.
