Can you provide a screenshot of the crystal you've used to craft the lens? More specifically its properties.

it didnt have any properties when i mined it which is the thing

it isnt a server i think journeymap or any other mod i have is the cause of it being considered one

@witherlink13 every minecraft instance has a server and a client instance, even in single player. It's been that way for a long while now. Doesn't change that the answer in that case should be "Singleplayer". Also need the rest of the information.

its a custom pack i have using nether ex, ad inferos, journeymap, NEI, draconic evolution, mystical agriculture and a addon for it, tinkers and some addons for it, project e, bloodmagic, botania, exteme reactors, thermal dynamics foundation and expansion, quark and an addon for it.

Well. yea. a crystal without properties causes this - most likely on more occasions than that aswell.

What type of server are you running? Forge? If so which version? What pack are you running? Anything that modifies EntityItems? Did you pick it up with some sort of instant-pickup magnet that might've removed the necessary data?
