Item behaves differently on server

So i recently just finished up my Ark mod, and everything seems to be working except the Railgun. It works just fine in the Dev kit, and on Singleplayer, but when it’s used on a server, it does no damage, and the X-ray doesn’t seem to be working. Does anyone know how to fix this? Perhaps it needs to be Child in order to work properly? I really need to know.
