I was in the maggot lairs lvl.3 and got killed. I was returned to town then I revived my companion and went back. Level 1 and 2 were the same but when I entered level 3 the map was all undiscovered! Now I can’t find my corpse to recover my gear!! I have not turned off the game or put it in sleep mode. It was only minutes between dying and returning to level 3 to recover my corpse. 
I tried to be as detailed as I could. Good luck out there everyone and stay rejuvenated!!
