Problem:
You can be stuck on page 2 of a battle that only has one page.

Reproduction steps:
When you are engaged in multiple battles and hit the battle tab button to view the different battles in succession, you keep looking at the same battle page number. For instance, let's say you are in battles A, B, and C. If you look at battle A, then go to the 2nd page, then hit the battle tab button, you are now looking at page 2 of battle B. If you hit the battle button again, you are looking at page 2 of battle C. The problem is when battle C only has one battle page. Now you are looking at the blank page 2 of battle C. There are no buttons present to switch over to page 1 of battle C.

Work around:
Go back to battle A, change to page 1, return to battle C. This might not work if battle A and B end before using the work around, I haven't had that come up.

Suggested fix:
Do not preserve battle page number when looking away from a battle. That or preserve it on a per battle basis.
