  Changes:
    - Updated the description
  Organization:
    - Refactored a good chunk of the mod to allow for more easily randomizing with a prototype-first method rather than property-first
    - The refactoring will, if anything, probably end up in more errors in the short term, but in the long term development of the mod should be much better
  Balancing:
    - Tile walking speed modifier is less random for tiles that don't normally have a modifier
    - Random crafting/running speeds are now rolled with a simpler, more balanced formula
    - Tweaked the lower/upper limits to be larger on several properties to allow more random experiences
    - Increased the maximum/minimum internal bias

Date: 2024.03.04
  Balancing:

    - Only randomized magazine sizes with a base size of at least 1, also removed negative bias on magazine size
  Bugfixes:
