I recently rented a server for Minecraft, specifically to play Attack of the B Team.
Do I need to add the addons in the profile addons tab, or are they automatically part of the world?

My second issue: I want to reset my world so it generates a new one, as I am not happy with my start location. The "Reset world" button doesn't do that, it gives me the warning then loads, but nothing happens and my world is the same.

Please help!
