TheEnd Bug

Well in TheEnd when i jump on the portal to teleport to obsidian plataform i spawn randon in TheEnd and i die because its close to Y:20 when i spawn and this occurrs more frequently..

2. when i tried to explore the EndFortress just spawn the land but not more the fortress.. i tried killing the EnderDragon 2 times to spawn more portals and just found 1 when spawn and no more for 10000 of blocks away in any direction!

pls fix TheEnd.
