Hello there!
Big fan of the beta here, great work
I haven’t seen this issue being raised, but everytime you switch instances by taking a waypoint or tping the instance you were in gets reset.
It is such a pain to see all the monsters respawn, the map completion progress reset (I am kind of a completionist and having the map reset when I went back to town to send some items was a big let down) and worst of all losing all items on the ground, even if you just do a quick back just to stash items to make space in your inventory.
In my opinion a system like Path of Exile where instances exist for 8-15 minutes would be very welcome.
Thanks a lot and cheers
