Viewport override bug when plotting

When I go to plot I'm not getting the desired result as displayed on my screen, in print preveiw I'm getting layers that have been overriden to be frozen, also, I'm getting a repeated XREF in 3 places.

I've tried deleting my viewport and redoing the overrides without success. This is annoying me, AUDIT does not help either.

Attached are two images, 1 of the drawing how it should be, and 2 the print preview.

Not of the contours should even be plotting but they are also duplicat as indicated in red.

Any ideas on how I can fix this?

You haven't accidentally set their layers not to plot have you?

Easily done, mate.

no the problem is there are entities that are plotting when they shouldn't be. Plus the two red circles indicate a random duplication of the contours in the middle of the drawing. These contours are in an XREF and these are frozen in my viewport.

Restart AutoCAD. Seems to be working now.

sometimes the crazy problems can usually be solved with a simple restart...I think ACAD sometimes does too much for its own good
