Donation problem!!

Hi, this is the second time I've encountered a bug where someone donates troops and does not receive them. This has only happened to me with dragons. 1 time a few minutes ago. And one time to a friend and I had donated the Dragon. Don't know exactly what's going on but please fix.

Whoever is donating has bad internet. The troops are gone, and the donation total goes up, which is registered by the donators' game, but the game sticks in an infinite loop trying to recieve the troop, but never does.
