I looked over the configuration and didnt see a few things, and im wondering if its something i missed.

Can scheduled/maintained events be specific diffuculties aka:

3 easy bases

2 medium bases

1 hard base

at all times?

and can you force materials to be in the cupboard (wood, stone, metal etc?)

i think yes ..

that will be max event bases "5"

and edit this percents :

{
  "Settings": {
    "Raid Management": {
      "Max Percent Allowed To Spawn Per Difficulty (0 = ignore)": {
        "Easy": 0.0,
        "Medium": 0.0,
        "Hard": 0.0
      },

about mats .. maybe you can just include it to the orginal copy of the base .
