I have build a REAL flying plane on my realm with slime blocks and redstone blocks and pistons, i need to travel to a place that is FAR from spawn with it, it takes 20 minutes to travel there. But then when it has been 15 minutes the realm kicked me and says "Connection Lost"
"You have been idle for too long!"

And when i fly my plane i need to be AFK, then when the message come, i need to log in again, then i'm crashing to the ground and dies and lose all my stuff!
PLEASE FIX THIS! Or i can never fly again! ;_;
