I have a custom bow, currently an exact replica, shoots the same arrows as the original, but I have a similar problem to this topic: http://www.minecraftforge.net/forum/index.php?topic=1751.0. When I shoot the bow, no arrow appears. If I get rid of the !isRemote, they spawn but do not act normal similar to that topic. Any ideas?

Also, just maximized minecraft after having it in the background, it works now, as before, but then it just stopped. Hmm...

 

Alright, I figured it out I think. So I have an item that changes into my bow when it's right clicked. The bow can't fire until I quit and rejoin. Why is this?

Alright, weird issue, they don't work until you view your inventory with E? Any idea why this could be? My code:
