the only major bug I have discovered are the times when the ship is a person when its suppoed to be a ship and also vice versa. Both are immovable when they are in their incorrect form. I took some screen shots and you I have seen it happening to other players in the game also, especially at Spacedock
This particular issue seems to be server side lag, as it were. Your character will become either ship or person as it is supposed to if you wait about a minute or two. It's almost as if the client beat the server to the punch, and it's playing catchup.
There are several threads about this already. It is usually lag, although I've heard reports of people actually being able to fly around and shoot and things on planets (every time its happened to me I am stuck in place).
