I'm playing on a server my friend is hosting, and I can't use NEI. It's not that I can't spawn stuff, I can't see it at all. There are no options in the bottom left, and no recipes for me to use. My friend, the host, is able to use NEI, idk what to do to turn it back on. Sorry if this is in the wrong spot.
