Has anyone seen any evidence that this is a limited duration event, or must be renewed periodically?
I hit Exalted with Tillers last Thursday, 10/11, and asked Jogu to come live on my farm, and he did. Today when I went to get my prediction from him, he wasn't on my farm, he was back in his pool by the market. (He may have been back there yesterday, too, but in my hurry to get stuff done after maintenance I may have just talked to him and overlooked the location.) Further, he no longer has the chat option to have him come live on my farm, while Gina Mudclaw and Fish Felreed (the farmer in town today) both still give me the opportunity.
Before I hit send I decided to try one of the others. I asked Gina to come live on my farm, and she did so almost immediately. Then I asked Fish to do the same. Fish responded, "My papa always did say to help out a neighbor in need! I've just gotta take care of some stuff here at the market, first. I'll be there soon as I can!" and Gina immediately disappeared from my farm and returned to the market. Fish didn't show up after about 5 minutes, so I went back and checked Jogu, and he had regained the "visit my farm" chat option. I asked him to come back to my farm, and he responded with, "I'll be right there... right after I finish this drink... hic!" It's been 15 minutes, and both Fish and Jogu are still in the market, not on my farm. I think I broke it.
Anyway, my original question: Does this appear to be something that has to be periodically renewed, or was Jogu's returning to the market in my case a bug or glitch?
