My colleague and I added Lists support to our C# Twitter Library (tweetsharp.com) recently and during unit testing we created several lists, expecting to destroy them with similar API calls during the test. The DELETE calls returned successfully but the lists were never deleted.
In fact, we can't even delete the lists from Twitter itself if we select them through our sidebar and choose "delete", which makes me think there's a larger issue with deleting lists in general. Has anyone else besides us experienced this? The lists otherwise function, they just don't respond to delete requests via API or Twitter.
