I checked and problem also exists in Creo M110.
We use a mapkey to do this whenever there is a problem. It is amazing the number of problems it fixes on old dwgs (we typically reuse dwgs via save as instead of starting new ones). I have been using it more and more routinely and have not yet noticed it creating any problems. For us it has been very good and fixed a lot of problems that would otherwise take much longer to fix or work around.
