I have filed a report on this but wanted to know if anyone else was running into this problem. three of us set off to remote areas of Ur.. Dutifully uttered the incantation in order, and if worked until it didn't three streets in a row... nobody on the streets but us.. . thought okay somebody must have been here alone uttering one of the lines.. but then a party of three came onto the street we had just failed on, and BINGO... incantation works... What am I missing?
