Also had something similar happen to me, I was in creepy crypts and went through one of the doors that activates with a lever. Regular map on the 'm' key was still updating. Mini map on 'tab' stopped updating after heading through the door. Nothing major but using tab is a little more efficient. Love the game so far though. Great job. Should probably also mention that this was in an offline game. Haven't tested online much yet, so can't vouch for that just yet.
