There are times where I want the mod active but not fully operational, for example I sometimes want to turn off the instant build feature or the no science cost or the no resources cost, basically it's where I'm designing a map and want to test it without rebooting TB, after testing it I would then make the actual map in the map editor, having to reboot without mods each time is just annoying, I'd rather just start a new game, design my map, save an instance of the settlement, test it without leaving the game, then create the actual map based on the save instance
