Think I have a gremlin in my system, strange things keep happening.

  Last few day when I do an Extruded cut about half the time on the 1st try it refuses to do the cut.  But acts like it did with no errors.  To get the cut to work I have to close then reopen the part.  Delete the cut Extrude, put it right back in again same plane same dimensions everything.  This time it works.

Before I put it back in I tried a rebuild and Ctrl Q.  I saved and closed the part.  Cut still was not there when I reopened it.  Deleted cut and Sketch for it.  And as I said when I put it back in worked fine.

  Any body else .
