Alright I use Reminders partly as my supermarket shopping list.
Today, my iPod (iOS 7) Reminders just kept doing weird things. As I checked items off, I wanted to move a newly-checked item from the bottom of my list up a few places, to a specific point. So, I did that. But then Reminders moved it back and unchecked it. Then I would try again, and it kept doing that. I tried checking and unchecking other items in my list to begin troubleshooting... and then when I tried other locations for that one item, it seems to work fine...but then sometimes other items in my list would then randomly become unchecked again and the one item would move back to the bottom of the list.
What's going on? I've never seen this behavior before. Why doesn't Reminders just set items how I want like in iOS 6?
