I recently added this mod to my preexisting world, and even though I had my weapon tech tree (shooting speed, damage etc) fairly discovered, installing this mod made all the related military tech reset. It wouldn't be much of a problem in a properly working factory, but I play on a cleared island with other continents overpopulated with biters, and what's more, I'm starving for resources and fully functioning factory. Now I am worried that I may not be able to reclaim any land, because I got starved a little of resources 😅
