Minecraft Realms will be forever bugged if you spawn mass amount of an item

If you Spawm a mass amount of an item, for ever cobblestone, it will completely crash the realm, it will not be able to backup, not be able to reset, and not be able to change the world. If you are unable to fix this can you atleast make it so i can get my realm completely reset but with the same days left as it is right now? I just since I bought it like a week ago and i dont want my money wasted.
