Using Corel 11 for Mac... Been constructing a highly detailed street map for months. Using Weld tool to create long rectangles to create street grid. Nearly finished I went to weld one section of streets to the large original grid and it wouldn't complete the command. I realized much to my horror, that the original 3000+ node street grid is now labeled a "control curve"!!!!

I've always used control curves for flowing text to an object...
and in the past I just remove the text and it becomes a regular curve again.

Using a fast machine, very few crashes, but map almost done and now this?

HELP!!

How did this happen and can I do anything about it?

Grateful for any input.
