Update:
OK, all seems well now. I had to get a member of my guild, Shadow to assist me. Somehow.. ownership got transferred to the 2nd character I made years ago, Thurstan. I only learned this after Shadow clicked the guildstone to view the information.
What I had to do:
1. Signed on as Thurstan
2. Transferred ownership to Shadow
3. Signed on as Jizaboz
4. Shadow transferred ownership to me.
More history:
This guildstone originally belonged to Kigger years back, but I think it was just a solo guild. It was by my old Yew mining shack he gave me. The guildstone was later transferred to me via Subcity after Kigger said he had no use for it. This was more than a "few" years ago
Moving the guildstone to another location to initiate another player "in the middle of nowhere" was what caused to the bug, I believe.
Thanks GMbob and Hemlock/Shadow for finally getting this fixed.
