Grab Tool Broken

I was editing something for a couple of hours and suddenly the grab tool stopped working. After messing with it I realized it was only moving in extremes, so if I zoomed all the way out and grabbed it would move the face a model height away from the rest of it. I tried doing Shift-G to shorten the grab and it worked. Now it’s only half a model height away. Do I need to reset the grab calibration or what?

maybe you have snaps turned on? bottom bar of 3d view, looks like a magnet.
