This is completely unacceptable. This mechanic is way too damn long to lose all the progress you made whenever a network or game decides to take a crap. I’m so sick of loot being locked behind Astaroth when literally every other boss is just walk in, fight, loot, leave.
Make a damn portal that saves the level of progress you’re in already. Some of us only have a few hours to play and having 15-30 mins of it wasted because “There was an error” is the fastest way to get people to just quit for the season.
