Hardened Settlements
Never worry about throwing an explosive in your storage room again!
With this mod you can control whether explosions break objects within your settlement’s defend zone.
Hardened Settlements adds a new option under the Settlement > Settings menu that will toggle between allowing explosions to damage your settlement or not. With this setting enabled, everything within the defend zone of a settlement will be completely blast resistant!
Open the settlement menu by right clicking a settlement flag or using the existing keybind (default "C"). Click Settings (on the far left) to control explosion damage, and click Defend zone (third from the right) to see the affected area.
