Randomly Lost Star Gems

I was saving a ton of star gems for later and got around 700 to 800, then I logged in today and randomly went down to 181... without buying anything. Sent in a ticket, but its a bug you guys should look into.

Same thing happened here! Arounn 900-1000 and down to 73

Here here, 1100 and some to 469 :*( No idea what is causing this. A concrete answer would be nice.
