Upon using wire cutters on any type of wired fence in survival, the server crashes with a nosuchmethoderror. Probably due to a reference to non-server code.

Notably the crash does not occur in creative mode.

Crash would be useful but your most likely right.

Block.getItem(World, int, int, int) is a client side only method

Yup noticed that as well, changing it to Item.getitemfromblock instead, just need to work metadata into it.

no, just pass in 'this'. The ItemStack constructor can take a block as a param.

That's true, I'll test it and then commit the changes
