I'm still playing through the game and may add those things later
Since my psu decided to die and take my motherboard with it, don't expect those anytime soon.
I appreciate if anyone posted screenshots with the mod.


Extra info:
Several Liberty Primes is #1 cause of CTDs in my experience.
Recommended values for each spawn point is 3-12 (15 is the max that i would go).
For obvious reasons big spawns like super mutant behemoths are disabled in interiors.
