Put the summary of the bug you're having here

What I expected to happen was...:
When throwing snowball, would expect to see it flying and do damage to mobs (this happens when the 'host' player throws snowball).

What actually happened was...:
When Throwing snowball, nothing happens (other than you are losing the snowball / count of them going down), can't see if flying, and obviously won't do any damage...

Steps to Reproduce:
1. Connect to wifi world
2. use snowball
3. throw it
