Appears the mpod is not performing a remote/client side check when calling the net/minecraft/client/util/ITooltipFlag class.

Issue is detrimental and will not run on server.

I have zero experience with servers, so it was kinda hard to test this fully. So far, it appears fixed in forge server, but if there is anything else, please comment here.
