Very funny! The first hint of at least an error was the price tag: 10.000 doblons for a tier X was a little bit too low to be believed knowing normal prices for other tiers and also the fact that it was a tier X on sale was also a little bit too much.
But with a normal price and tier IX, maybe it would have been easier to believe but again, the ship architecture made in ice was the final wink to indicate it was a prank and for the proximity of 1st of april, an april fool joke.
Finally, the purchase button did not work....
A pity we can't buy it!
