NEI spawning items

[Mike724]

For some reason players have been able to get items. For example one player keeps getting quantum amour, enchanted tools, ect, when he dies and respawns. Another player got nukes.

I believe this is a problem with NEI. Is anyone else noticing this?

Launcher/pack Version: 3.0.4

Operating System: Ubuntu 12.04

Version of Java:

java version "1.7.0_04"

Java SE Runtime Environment (build 1.7.0_04-b20)

Java HotSpot 64-Bit Server VM (build 23.0-b21, mixed mode)

Description of Problem: NEI allowing players to spawn items
