Suddenly, when I pan around my model in edit mode, it vanishes. Then I can’t make anything show, even if I leave edit mode. All the other objects are fine. But one object, if I go into edit mode and move my view, the object vanishes and so does everything else including the background grid, and if I go back to object mode, everything is still invisible until I reload the file.
Bug or some weird setting I don’t know about?
