Hi, since yesterday have disconnection issues, when im changin locations or trying instant buy from trade something taking disconnect, its like 8-9/10 times and it's very annoying. Now reinstalled game, and deleted all old files, tried STEAM version and nothing help, called even my internet provider and he reset my router and said is with my connection is everythink ok. Its something happen with ingame servers in PoE Mirage? Any advice what i can do? because now game is unplayable for me, and im really enjoying leage :-/
