No gem after completing level 4

[moo8moo]

I just completed level 4 for white peach tea, but got 20,000 coins instead of 1 gem  what happened? So disappointed.

Ugh... yes that happened to me too just now
and it was also on the white peach tea. I hope
its just a glitch and that we can still be able to
get gems on the 4 completion. I doubt we'll get
that gem back though. So sad.
