I'm not sure; they might have. The base view of that set was pulled off the
side face of the ladder rail. It's kind of odd what happened, because the
views themselves followed the assembly fine, and are still just as they
should be. The annotations have all gone off to la-la land. They're
perfectly positioned off in space, not orphaned, just attached to nothing.
That seems like a glitch to me, not just Inventor getting honestly confused
because Walt did something really weird.
I sent the files into my VAR; Autodesk should be getting them. We'll see
what happens.
