If I port to sell some loot, there should be a grace period of at least a couple minutes in which I can return to an area in the same state in which I left it.
I port back in and my map discovery progress is reset and the same mobs I just killed have returned and are surrounding me when I port back to the map.
I know,. Its beta. Theres too much porting around as it is, make it feel like a more fluid experience and save map progress when using town portal.
I noticed this also. Seems really strange. I wonder if this is still the case if you’re playing with a friend who doesn’t go back when you do. If so, no real reason it shouldn’t work the same way for solo, except maybe server load / architecture reasons the player should never really have to worry about.
