Thanks TomC! This is actually something some of *us* have been confused over as to how it happens. We're going to do something to make it less confusing to everyone. :)
I'm pretty sure that there is another scenario going on that is also currently causing no gravestone to appear since there have been two stretches of time when I've had no gravestone, but neither of TomC's claimed scenarios were true for me.
Bruce, do you think perhaps you had a tie with 2 or more giants having equal and also the highest favor out of all 11 giants? Maybe because of the ties, the game couldn't decide which giant to put on the gravestone.
No, please see this comment I made in reply to you previously: http://www.glitch.com/forum/general/11682/#reply-120914 I checked this right after seeing your comment last time since I had no gravestone at the time. My capacity with Tii is my second largest one overall and that favor value is larger than most of my other giants can hold except for Alph, which was less than that at the time. (I will note that I have come in line with the symbol representing the giant with the most favor since last time I commented on this; I just suspect there is another possible condition set creating no gravestone whether that is intentional or not.)
I have a hypothesis currently that it's associated with having Tii as the giant with the highest unspent favor. I once again have no gravestone and it started after I got my most recent Alph emblem. My unspent favor is as follows:
Last time I had no gravestone was also when I had Tii as the giant with the most unspent favor and that ended when I got my Tii emblem (at which point I believe it reverted to Alph appearing on my gravestone since he was then the giant with the most favor).
