On the 25th or 26th March 2014 i bought £25 of gems in the 3X deal (16800 gems). On the 28th of March most of them were gone. I worked out that they had been used to instantly upgrade 4 buildings. I contacted support as i knew i had not done this. They confirmed the amounts and time the upgrades were done. 2 nobles from level 3 to 4, a gold smelter from level 1 to 2 and a friary from level 4 to level 5. All four were done within a minute with the buildings spanning from (using 1 on the keypad) the top left corner of sector one just off the screen to the top right corner. I tried to let support know that me or anyone else with access to my computer could or would have done this, that the upgrades made no sense to my economy anyway and i was happy to destroy the buildings to get my gems back. They investigated and said there was no bug or glitch that caused it and it was done through the UI and confirmed each time. I again tried to say i didnt do it, they made no sense, id destroy the buildings for the gems back and that i still had to spend the gems in game so neither BB or Ubisoft would lose out on money but they again refused. Im after any help i can get really, if there is any, as its a lot of gems to lose that i cant afford to.
