For the second time I have completed the in game challenges and collected the items required to collect bonus rewards, the first one was the dog towards the end of Tokyo, I was required to collect 10 collars for a reward of emeralds, no reward was given even though by clicking on the dog it shows that all items have been collected, the second time is in San Fransisco towards the end where I had to collect 10 items for Rosie riveter, collected all items but no reward, supposed to be 150 coins.
