I'm not sure if this issue is new or possibly related to issue #3762, but when I upload images from twitter via the batch uploader, the source is set to the direct image link rather than the twitter post. I have to set the twitter link manually after uploading, as changing the source in the initial tagging/upload step removes the commentary.
I know that for pixiv sources, the source is the direct image, but the post links to the pixiv post, are twitter sources supposed to behave like that as well?
