1.7?

I found a spawner and inside one of the chests was a luck of the sea II enchanted book. But when i try to take it, it sayd (Disconnected from server) so then i just destoryed the chest and got it. But now i cant throw it or put it in a chest if i move it i get kicked. Its weird is it just a 1.7 glitch with the server cause i noticed in the darkoak forest all the big trees are gone... anywho just thought i would report this bug
