I've been paying the monthly fee for my real to play with my friends for a long while now. 
im on this every day and all the time. The issue I've encountered is after I beat the end dragon and took the small portal to the end islands all five of us made it through we got all our loot we wanted and headed back. We arrived at the small portal to take us back to the boss fight location. I and four of my friends made it back but 1 was instantly thrown into the void. He lost all his items. For a long time I never went back but I eventually had too. On my attempt to go to the end islands I was killed as well and lost all my items to the void. Extremely frustrating when I pay for this realm and constantly run into bugs such as this.
