What gameplay feature is this bug affecting?
Caves

What's the issue? Please include any error messages you receive and as much detail as possible.
I have two accounts, both of which have caves that are built (the first three slots). On my second account (#59195), I can click the left button on the Unsorted page and it takes me to the last cave that was made/ the last alphabetized name. On my first account, (#58310), I cannot do that. I can still access the last cave from my Den Page and I can click on the right button from the previous cave, but I cannot do that from my Unsorted page.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?

Pressing the left button takes you to the second cave on the list, not the last.

Any screenshots you can provide us with?

You might be able to do this on my Den (#58310). Go to Unsorted and try clicking the left button to take you to the last Cave. It will take you to the second, not the last.
