The Tiger adventure for 2015-2019 is My Tiger Jungle. Currently in the calendar under planned advancement, it is titled “Backyard Jungle” which is the old title.The requirement numbers and descriptions match Backyard Jungle and not the renamed My Tiger Jungle. Hope this makes sense.
Also as another bug, when adding the requirements for planned adventure, if you add ALL requirements, then graphically under the name, the requirement numbers show (in calendar edit screen). If adding less than ALL requirements, it does not display the numbers. I will attempt to add a screenshot.
