You messed around with wibbly-wobbly timey-wimey stuff and now you have the consequence. Your Ghazt is FROZEN IN TIME!

Just leave it for a couple of days, perhaps it will be normal once it has caught up with its proper age. If the problem persists, I guess you could try changing the tablet's clock again, forward and backward, doing nothing whatsoever except try to select and sell the Ghazt. It's not doing you any good as it is except as a kind of decoration.
