AutoCAD 2014 takes forever to save my blocks after editing them.

Ok so here is the scenario:

I am desiging a few electrical cabinets and I have been importing my cabinet templates from the mfgr .DXFs. (Schaeffer's Enclosure to be precise) 

For some reason, it takes me a while to save my blocks after edits. 

I don't recall 2013 being that slow between edits but this time around it's taking well over 1:30 minutes to save one block.

It's just ridiculous. Any idea?
