So I'm Working on my mod called ECKO which stands for Energy Cell Killer Overhaul

I add some new ammo types to energy weapons then realize I still need to add them in the ammo list so my spread and focused cells can be used alongside the normal, overcharged, and max charged cells

Whenever I try editing anything with a List of any kind the GECK crashes. I have no idea how or why this is happening.

Any pointers would be greatly appreciated.
