Yesterday pre event I had 9,600+ gems.

Today I log in to find at least 1500 gems are missing, I now hold 8,574 as I type this.

I have 3 gem pits running so the number of gems missing is probably a lot higher than 1500 taking into account production from the gem pits since yesterday.

I know the number of gems in hand because it's written on my island by me everyday (because I don't trust BB)

Any chance of getting back my lost gems?
