I'm getting a strange DWG corruption (actually sticks with the file). I've seen it on one other machine and for the first time today on mine. The file was fine for several days and then it just corrupted, the only thing I can do is copy the information to a new file, not an ideal solution by any means. Regen sometimes makes it better, sometimes worse.
It seems removing some objects, saving the file, and then reopening helps some.
Any thoughts?
