I have completed two jewels and can't receive my gold bars.

Just wanted to follow up. I completed another piece of jewelry today and received my gold bars with no problem. Thanks for getting this fixed!

Music to my ears!
Many thanks for the follow up! 

As the issue with not receiving rewards in Facebook is thankfully resolved, I will close this thread. It is just to keep us updated on things - if you have issues with rewards in the future you can always open a new thread

Thanks for reporting
