I used a crystal in my design from the SparkFun library without properly checking it. The schematic has two wires, but the footprint has 4 pads.
Unfortunately I have already had my PCB manufactured and only two of these pads are connected to my IC, so I'm hoping that this crystal will do the trick:

However, the datasheet says that the two pins that are not connected to the crystal should be grounded. This is going to be tricky unless I start hacking at my PCB's with a knife to fudge some sort of connection to a ground plane.
Old crystals had only two pins by design. What will happen if I don't connect the two ground pins for this crystal?
