So, I assume we are all experiencing the random invisible object.
(I suspect a problem with loading the .x files.)
While discussing this with a colleague, the possiblity of an invisible asteroid came up. Hmm.
An invisible starbase I can recover from.
An invisible planet, at least it shows on radar.
An invisible ship, shows on radar and has its engines.
But an invisible asteroid. Who would know? Until you drove into it while navigating an asteroid belt. And, of course, it would be dead smack in the middle of that open patch you are flying through. Why else would it be open?
Just a paranoid thought for when you are flying through those all-asteroid systems....
