As said in the title, when I drop my weapon in-game it spins around forwards and sometimes stops. It won't easily stick to the ground like a normal weapon, and clips through it but not going right through. This is one of my first few meshes with Blender, so I'm not really sure what I did wrong. Can somebody please take a look at http://unforgiving-parasite.net/dagger.rar and explain how to fix it? Thank you in advance!
