So I noticed and tried them a few times and seams that maybe some hooks changed or break lol.

1. if you fall into a void (past bedrock) you will die and this really sucks because we never had this on our 1.1 server with WG)
2. dispensers with arrows cause dmg.
3. tnt causes player damage
4. ghast cause player damage
5. skeleton archers cause player damage

Hope these can fix these the 2 major ones for me will be void and dispensers.
