My colleague is having issue with block. First, we thought it was gone but then discovered it is in the drawing but it is not fully visible. We can see some flanges but other parts are not there. I tried to explode it, check layers to make sure nothing is frozen and have no luck. Also I copied it into brand new drawing and it looked the same BUT when I exploded it, I could see all the parts. I tried to wblock original file, nothing has changed.
Any ideas what it could be?
