TE pipes laid out in the overworld imprint on the moon?!

[Entripic]

So I teleported to my moon base via mystcraft books, and I noticed random patches of itemducts, liquiducts, and energy conduits around the base and they looked exactly how I piped my machines in the overworld. Is anyone else dealing with this weird anomaly? I went to them and they are legitimate items. It is hard to believe but it is true.

I have this too. But when I log out and log back in they disappear.
