Server Rollback

I just completed a map then i opened a breach after i already killed all the rares and got a map completed text . Then the game froze so i went back to the log in screen . after logging back to my character all my progress has been wiped, i got no map completion and my inventory was empty . none of the map loot was there. i lost exalts. since when does poe have such server roll backs, i didn't even get to keep my loot. not to mention it counted as a death and i lost 15% exp. so pissed about it. this is garbage. WTF GGG
