There is no edit I made the screenshots today while I was playing!
I don't know cuz I'm not the one who made this mod BUT the lightsabers do thril and hit with both sides!
Maybe they do act like single one's but now they are double-bladed and if your char waves the ''single blades'' with the other end it looks like he hits with the other blade.. ( I don't know english very well ) You know what I mean..
