If I fully investigate a map, leave, and then come back to that map the minimap has the “fog of war” enabled (as if I never investigated it). The monsters in a given area respawn over and over.
Here is a quick video of what I am experiencing. By looking at the minimap you’ll see that I’ve explored the current area. Then I enter a door and immediately return to where I was. The minimap fog of war is back like I never explored that area.
At this point I don’t feel like I can continue playing since I have to fight through the same content over and over.
