I and several of the people in the outfit see floating objects after changing continents. While we no longer crash (as often) after changing continents, the floating objects seem similar in reproducability as the out-of-memory crashes. Simply put, you just need to switch continents enough to exceed the 32 bit memory limit (while on the 64 bit client). This seems to create the floating objects. The objects in question can be rocks, parts of bases, etc. An outfitmember even landed his Galaxy on top of a floating landing pad, upon which he could leave the galaxy and walk around in mid-air. The rest of us would simply fall to the ground when exiting the Galaxy. You can get rid of the floating objects by simply relogging.
