I recently switched to Forge, since I was running out of space for icons and such so I am a little new with this. However, my Error seems to be a little strange. Whenever something like my custom bow or a knife is thrown it doesn't spawn into the world correctly. if I leave !world.isRemote like it is I can't see my arrows/throwables, but they still work like they are supposed to. However, if I take out the ! then I can see my pictures, however they do no damage whatsoever. They even just bounce off the mobs or if they explode they do no damage. I have a lot of items, so I will just post the three important ones.

This same problem goes for items that use icons to render, although the icons that are used sometime appear as something completely different... like Chain Boots. Hopefully this is enough information to help. This and my teleporting glitch is screwing up my game without giving actual errors, but that other glitch is for another time.
