Is this a new behaviour? If you trigger an AL trap just before exiting a street, a bandit may appear in the new street when you enter it. Promptly snatched my favourite Daiquiri, too. Stupid bandits.
I had this happen a couple of times, usually somewhere at one of the Tumble Roads, can't remember which one precisely. I swear I could hear it laughing, grrrr
I had a bandit nick an Awesome Stew the other day, cos I got 'stuck' when the new day arrived ~by the time I had clicked 'ok' to the new day, the Juju was gone...not an awesome experience, and it left me stewing over it -until the next dust trap gave me a very fine goodie. lol
eta: and just what do you do, when a Juju is after your Diamond, and Rube appears wanting to trade...?!
