Trying to open a world results in the screen quickly flickering between the map menu and the map loading bar.

I won't lie, I don't know the 'affects version's so I clicked on the top option. When I try to open a world map in that menu my screen flickers non stop between the map menu and the map loading bar. After a handful of times of this happening I back out to the PlayStation menu put my controller down and walked away for a minute. When I went back into the game I was in my cave in a loaded game. Help?!
