I have fairly large assembly that was imported from a vendor and with it open SW has crashed 3 times today and multi entity-selection is SLOOOOW. I haven't crashed 10 times total after installing 2016 so this is weird to me. Since this only happens with this assembly open I feel like it is a corrupt file within. Is there a way I can find out which file is bringing me down? I tried using assembly visualization and looking at rebuild times but that didn't give me anything.
