Yeah, the hovercraft thing is something about desynch and restarting usually fixes it. HOWEVER: When you hop out of your hovercraft while pressing direction keys, it floats a little just into the direction you've pressed. So, for instance, if your hover spawns in hangar bay 1 and you press A and W and jump out while still pressing the keys, your hovercraft should slip right out of the hangar, and you can usually get in and drive it around as soon as it's on non-hangar ground. Repairing's a little harder as you have to play around with it a bit to actually get it where you want it in the bay, so that's where restarting's really starting to become a viable alternative. Also, quite often it works to get out of your hovercraft and have somebody else drive it out of the hangar for you, but of course that's not a solution to be repeated too often.
