I turned down all the trades and got the quest. I encountered the Rube twice before going home. I don't know if the quest would have appeared after the first non-transaction.
Fun little quest!
I summoned the rube with essence of rubeweed, traded with him and went to my home street. Nothing happened so I went back to world and kept exploring. A little while later, maybe 10 minutes or so I used a visiting stone and about 30 seconds later when I was on someone else's street the quest popped up. I do't know if it was just slow popping up or if it was waiting for something else but I got it.
i wasn't really paying attention while doing this quest, it said something about finding wrizzards in 10 seconds, but i took way longer to do it since i had to first figure out what is a wrizzard. but i still finished the quest and got my bonuses....what's with the 10 seconds, extra bonus or i was just hallucinating?
Got Rube after q was introduced, picked his 3r offer, no quest. And while ago got him again, this time went trough all 5 offers and finished with no thanks, zoned to my street, got q.
I just completed the quest, and I don't know how the quest appeared. But here's a tip: if you've got the Eyeballery skill and a camera*, you will have good success in completing it.
*Possibly just pushing "i" on your keyboard will do the same.
I summoned the Rube via imbibing essence, rejected all five of his offers. (not for the quest, they were all just really bad offers.) Went on with my day, bounced between house and world a view times. Start of the next new day, I had "1 completed quest", but I never got the notification that I had one in the first place. IDK what happened. :<
