as we were packing up, he left it on the table to pack up his models and the codex was probably mistakenly taken by another player.
if you have the codex, (its a brand new book, no name etc) please bring it back to the club asap. my friend has just started playing 40k and is quite upset at the loss of his codex
hope you guys can help! im sure its just a mistake that someone made
Cheers!
