I have a problem with uploading my world. Whenever i try uploading a world it just gives me the regular '''super flat'' world. I saved my file as a .zip and it is not more then 50 mb.
infact its alot smaller then that. I spended alot of time in a project wich involves command blocks, Redstone and a huge building. But now i cant play it with my friends 
If anyone has a solution to this problem please comment on this thread.
