[BUG] dupe bug with multishot crossbow inside non-mcmmo worldguard region.

[Dawlnken]

If you shoot at the ground in a angle to make the arrows bounce, when the arrows hit the ground it should not be possible to get them back. But if you are inside a worldguard region with mcmmo off (/rg flag rgname mcmmo deny) you can pickup the extra arrows, duping them.

This can be a problem for servers that have areas with mcmmo disabled and players can bring itens in and out of the area. If the server economy allows arrows to be sold, it will be an money dupe too.

To reproduce:

1. Create a region with the mcmmo deny flag.
2. Get inside the region
3. Shoot the ground with a multishot crossbow in the right angle to make the arrows bounce
4. Pickup the arrows
