I have 65 plugins, when I use a plugin to transfer between worlds. I have used 2 different plugins for this. I am in PMMP for MCPE 1.2.13
Maybe all the plugins are causing too much lag to allow you to move worlds. Maybe its due to TWO WORLD PLUGINS there at the same time. Maybe its due to you simply updating a plugin's api, without checking if the imports have been changed Maybe it would help if you give us more information.
Which plugins did you try? Are there any error messages? Well I'm sorry, but you need at least 1 world to play on a server (or on single player, for that matter).
You know that you can edit posts right? Do you have both of the world plugins installed at the same time? Also, what world format do you use?
Please, just tell us all the information instead of holding back. It make's it harder to help you otherwise.
