Brass and Blades

v 1.1 -> v 1.2
- Removed Guard Villagers (they tick badly when the villager come into simulation distance and i'm worried this could cause crashes when combined with create machinery running in far off chunks)
- Patch for compatibility between steves icbm and immersive engineering.
- Silent Gear added

- Big Papa missile reintroduced as the most expensive and destructive missile.
