This is an odd one.

I attached an xref in my drawing, when I try to freeze a line in the xref it wont let me. It says the line is on layer 0 and is the current layer and I cant freeze it. Even when I xlist the line it says the line is on layer 0. I went into the xref to see if the line was on layer 0 and its not, Its on a contour layer.

So I put my xref on a new layer called C-DASH, and when I select a line in the xref to for some reason freezes layer 0...

So I cant freeze any of my xref lines, because it says theyre on layer 0, even though they arent on layer 0.

Anyone run into this?
