This will add back in the rearmable deadfall traps that were removed a few versions back.
This mod does not replace the current spike traps but adds deadfall traps in as a second choice. They do less damage, cost more to make, and take more time to build. But not having to spend so many resources maintaining a defense should be worth it.
Most of the logic is copied directly from the b18 version of Rimworld, so behavior should more or less match how it used to. Including the ability to place them right next to each other.
