Plugin resets config with each server restart

[CorpseKitten]

So when starting the server or reloading configs the file overwrites itself with an empty one making the mod completely unusable

This is what it gets replaced with

# 
# if true - plugin will summon chest with spent resources under tree
core:
  holiday-ends: {}
  plugin-enabled: false
xmas:
  tree-lvl:
    sapling:
      lvlup: {}
    small_tree:
      lvlup: {}
    tree:
      lvlup: {}
    magic_tree: {}
  luck: {}
