This mod version is only for those of you that moved to the IWBUMS Unstable branch (version 41.73 In this case). If you are still in the version 41.71 then make sure you are using the main Snake's Mod Pack.
This mean that if enabling sledgehammer destruction is a pain in the butt for your server, between this mod and with how now all player built tiles can be disassembled, and as long as you don't want stair cheese, there is no reason to have sledgehammer destruction enabled for your server.
This is a mod that aims at making combat more fun and realistic, making weapons and guns behave more like how you would expect them to do in real life.
You can access this feature by either right clicking a corpse, or right clicking the ground if you are already carrying a corpse. You will see the "Grab-Dump Corpse Control" button in the context menu.
