On fire os 5.1 on an amzon kindle fire hd 7 rooted device the server crashes when chucks load up and it closes down the game I have tested on 3 different servers bounty hunter lbsg hunger/survival games lbsg and my private sever to play with friends it has happened 14 times already if any else has this problem post here.
Unfortunately, the way that 3rd party servers manage their worlds is not part of MCPE and can't be fixed by Mojang.
