Diamonds and only disappearing

Used to play this game a lot, then took a break. Had 124 diamonds when I started back up 2 days ago.

Now the diamonds I had automatically disappear. Down 60 diamonds in less than one day (I actually used 4).

These are the kinds of glitches that should be caught before production. Recommend staying away unless you enjoy saving for months and then having things just randomly disappear 20 at a time
