Loading different savefiles doesn't seem to clear the data from the old savefile

fix it

more info: during the recent OrbitX demo, there seemed to be some state that was not cleared after loading different savefiles while the compat client was running.

I forget what state it seemed to be, possibly fuel? which was maybe communicated from OrbitV engineering through the compat client.

To close this issue, first we should actually investigate if it's a real bug or if I'm just crazy, by loading a new savefile and checking that nothing persists from the old savefile (object positions are definitely not persisted, but there's a bunch of other pieces of data like fuel levels etc that might be persisted)
