So i tried again today, with main proxy and EU proxy, and i'm still getting disconnected, just with EU proxy i can play a little bit longer. And yet i'm still getting disconnects only while picking drop.
No errors, it's just disconnect. also tried to play with lower details, but it shouldn't a problem, my pc can handle high graphics.
1 more thing i noticed, when i got this "freeze" before getting disconnected, i can see chat still going, mobs attacking me, i just can't do anything.
