I was pinged on an sockpuppet investigations case and the Echo notification read: "Bbb23 mentioned you on the Sockpuppet investigations/Engboy142 talk page in "Clerk, CheckUser, and/or pa..."."

SPI cases aren't talk pages, so my instinct was to go and look at the talk page, but there was nothing there. I scratched my head for a while and then realised it meant the main case page. It probably shouldn't say it's a talk page.
