Changing dimension freezes the game

[Bertrahm]

Hello,

so after my last post I succesfully created a void dimension, only problem is that if I try to teleport to it (Using an item that has an onItemRightClick event that executes player.ChangeDimension(2)) the game freezes in the loading screen and gives me an NullPointerException.

However if I were to restart the game I'd appear in the dimension totally fine! 

 

Here is the error:

how looks the line of code that the NPE points to?

[Bertrahm]

Sorry for the late reply, but heres the line in the VortexManipulatorClass

player.changeDimension(Dimensions.ID_TARDIS);
