Playing on Plarium.com  at Untamed Lands about 1 hour ago.  Clicked on Black Market, more than 40 legends for half price. Bought 1 for off infantry, 1 for def infantry--got them OK.  Bought 2 hydras, they did not arrive, but saphires were deleted from my stash.  Refresh did not help. Bought one more hydra just to make sure I did not have 4 instead of 6 to begin with.  Again, saphs were deleted but hydra did not arrive.
