arcgis desktop - Points disappear when zooming past certain scale in ArcMap?

My points are disappearing when I zoom in past 300,000 in ArcMap. I tried to repair geometry, but it doesn't fix anything?

I also checked the scale extents and those are turned off. I can export the points to a new shapefile/feature class, but I'd like to not have to do that.

I'm using 10.1 on Windows 7 x64.

Answer

I ended up exporting the file and starting over with a new shape. It seemed to work. It could have been the spatial index since I ended up starting over.
