Iv been having the same problem and I to found a better solution. If when you load back up your scene you find that your geometry is missing!! Just simply go to the ( The "polySplitRing" Tab in the Attribute Editor. Now scroll down until you see the tab ( Profile Curve Options ) just untick "Enable Profile Curve". Your Geometry should reappear

Maya has a serious bug inside the " INSERT EDGE LOOP" tool and also the "Multi Cut Tool".
Hope this helps
