Have the had the same issue - clicked on tree when gift box was showing - got spinning hourglass and then nothing. Can't tell what I got - doesn't seem like anything new appeared in star menu and I keep a close eye on what's in there. Needs to be some sort of mail as suggested to state what item has been received.
Agree it is not fair to pay for tree and have NOTHING happen when clicked upon.
Needs to be fixed ASAP!
