Crop Overlay vanished

I was working on a large batch of images and suddenly in the middle of everything, my crop overlays vanished. I restart the program several times and it did nothing. Odds are good that I accidentally hit some keyboard shortcut combo without even realizing and it turned something off. I seem to do this often with each new update, when keyboard shortcuts are created that do things I didn't even know were options. It's insanely frustrating. ANYWAY ... I've attached screenshots of what my document looks like when the crop tool is activated - it should have the outside/corner boundary markers and the rule of thirds overlay showing, but as you can see, nada. But I know the tool is active because when I try and click or drag anywhere, it either moves or rotates the "cropped" image. I've also attached what my crop settings are. Please help, this tiny thing is making me lose my mind.
