@Jeraal There is a prefablist in the resource folder that comes with Nitrogen its a simple text file. You will need to look up values on all the WOTW prefabs in the prefab editor in 7D2D.
--------------This is the Vanilla Location - It is where places spawn when using Vanilla map generator.

There are a list ----^^^--------------------------------------------------^^^^^^^--------------of places in the Nitrogen prefab list That you can place them to spawn much ----^^^--------------------------------------------------^^^^^^^-------------like the vanilla list in the first part. Be sure the , and ; are placed correctly.
----^^^--------------------------------------------------^^^^^^^
This is the name of the prefab. -------------------------^^^^^^^<<-The first zero is the rotation to face north.
---------------------------------------------------------------------------The second zero is the Y offset, you will have to look up these
---------------------------------------------------------------------------numbers in the prefab xml file when filling out the prefab list.
---------------------------------------------------------------------------The next 3 numbers are the X,Y,Z numbers and can be found
---------------------------------------------------------------------------When the prefab is loaded in the game prefab editor. They are
----------------------------------------------------------------------------the 3 numbers in the upper right when esc key is active.
You will have to go through all the prefabs in WOTW and put the information in Nitrogen prefablist. I just use the vanilla list for mine but it is customizable. Make sure all the WOTW prefabs are in the vanilla prefab directory. I am sure there are other ways to probably do this but this is how I did it and they spawn in Nitrogen no problem.
