Using the same way you forceop with CreateYourOwnMenus, you could bring items such as command blocks, super enchanted items, named/lored items, and skulls into the creative server. You couldn't forceop but you could bring those items.
I used the bug to get command blocks just to show you that it works. I deleted them right after.

Edit: This is a major bug, it can be used to gain op. Party, if you want I can show you how I would use them to get op.
Edit x2: Bug patched.
