That's a strange one. Does it happen consistently? Did you add any other mods before this started?

It happens literally every time. A workaround that I have figured out though, if you create a new world and then immediately save and quit to menu, then open it again... the NPE doesn't happen. So that is pretty strange too. I was browsing through the SHPlayerDataHandler class, and think I have an idea as to what is causing it (which is what lead me to the workaround)

This is with a few other mods, and I am working on the process of elimination, but it might take a minute to narrow it down.
