[Strange artifact floating around my Soviet-style ships]

OK so what I have now is a docked pea and pomegranate, and it's in the correct place on the pomegranate and yea, that looks right.

 

I undocked the pea, and suddenly it had apparently picked up the docking marker, or a copy of it, which is floating a couple of meters away from it not attached to anything.  THAT''s the oddity.

 

I also saw one floating around not attached to anything, outside the onion capsule.  The one that is sitting in the correct position on the pomegranate is the only one that looks right.

I think the pea (2-seater) is the only one I've seen it on now that I consider it.  Sometimes it stays in that window, and another time I saw it kind of crawling around outside. 

 

It does look like it's meant to be looked through, so I suspect it has somehow detached from its normal spot and is a bit lost.

I believe this is a bug, and I am not sure where it's coming from.  I have put a capture of the mods I am using (though it showed up not long after I started playing and I had only a handful of working mods).

 

This thing floats around outside my Soviet-styled capsules  It looks cool but not floating in space irrationally.  I wonder has anyone else seen it.
