It was an attached library object. I removed that object and then there was this pesky triangle!

Sadly I don't own this ship, so i can't have a look. Is it free avaible
anywhere?
It is visible in the sim! Otherwise I'd let it rest.Attached objects have to have a polygon for them to display, which is usually called an "empty", as although it is drawn it has no visibility or geometry. Although MCX can see it, it's worth compiling and checking in the simulator, as it probably will be invisible.
