I'm not sure if this is just lag, but often it lasts for about a minute before my character changes. When I beam down to a planet, a lot of the times I'll spawn as a ship, on the ground. Relative size of course, but I'm a ship with all the animations, and I move VERY slowly. I do have the Ground Action bar though.
Same thing for beaming back up to space, I'll stay as my Ground Character for a few moments.
It's an Incredibly "common" problem. And I'm not sure if part of the issue is code related or not. What I do know is that it happens far less frequently when it's in the middle of the night and the Server Load drops off.
