Help with world

[MrJimJam]

So i added a world and i do /worlds then click on it to go to that world but when ever i die it sends me back to an other world even when i set world spawn in the other world, how do i make the other world the main world so that i wont need to keep typing in .worlds and teleport when i die?

Try going to your server panel, then go to the server properties section, then scroll a tiny bit down until you see "Level Name" and type in the world's name that you want to be the main world.

You have 3 **Default** *worlds : world, world_nether and world_the_end*, they are all linked together... 
To make a new uploaded world *Default* :  **Stop** server then go to **Server Properties** then in **Level Name**.. *Change* that name to the new uploaded worlds name.. once changed and saved, **restart** server, it will then create new *Nether* and *End worlds*, all new worlds will be *linked*  to each other, you can then **delete** the other 3 worlds, i.e *world, world_nether and world_the_end*.... (on a side note all playerdata saved in default *world*, in playerdata folder)..
