All, this is a bug (or unsupported) in twitter’s API. There is a point in most people’s favorites history that the API just stops returning results. Often you can see the same “missing” favorites on the actual favorite list on Twitter.com. I hope to find a resolution, but we are stuck with it for now.Jessica supported this idea ·Jessica commented
I am having the same issue. I deleted about 2,000 tweets and it said I reached my limit and to check back 15 minutes later. I did so and deleted about 20 more favorites and then no more appeared. It has been about 2 weeks and I have checked back daily to see if the problem had been resolved. I tried on Chrome, Firefox and even Internet Explorer and for some reason I can't seem to get any more of my tweets to pop us.
