_FORZA_

I was playing on my server and I found a command called /worlds. I clicked on one of the choices and it teleports me to a different world. I try going back through this command and it says the world does not exist. I go to discord help channel and they tell me to change the name to something with no spaces and no caps and I do so and it creates a whole new world and i lost all of my stuff. Is there a way to get my original world back or a way to change the name of that world other than going to the dashboard so I can use the worlds command to teleport back?
