On a few occasions now I have found that I have not received the 3 free Tickets. On all of these occasions I've had a fairly large (~20+) stash of Tickets -- is there a threshold above which one will not receive the 3 free Tickets? and, if there is, do any of you know what it is? I suspect this may have already been answered elsewhere but, if it has been, I cannot find it on Wiki or by searching this forum.
