Bukkit

What steps will reproduce the problem?
1. Introduce the feature that even renamed items will be taken from the player's inventory when /lottery buy.

I expect for the diamonds to be taken away. However, they stay in the player's inventory.

What version of bukkit and lottery plugin are you using?

Craftbukkit 1.8.7

Are you using any economy plugins? If so, which?

No, we try to keep it vanilla.

Do you have an error log of what happened?

I do not have an error.

Please provide any additional information below.

Hello,

I have been in love with your lottery system because it allows my SMP to have a lottery without an economy. I have used diamonds as a currency to purchase tickets. However, some people are abusing a glitch to not get their diamonds taken when they buy a ticket. If they rename their diamonds, when they do /lottery buy, the diamonds will still be in their inventory. Can you please fix it? It would mean a lot to me.

Thank you.
