Tiptoety renamed ProudJain to RightBKC. As the rename did not move the userpage and talk page, Tiptoety manually moved the user's enwiki talk page and user page. Later, the Rename extension finally moved the page (again).

Now the content is nowhere to be found. There's some content in the deleted history of User:ProudJain, which had been deleted previously, but there seemed to have been a later user page and there should have been a talk page, and there's no trace of it anywhere.

I looked in the logs, the deleted history of both pages, the deleted contribution history of both user, I couldn't find anything.
