Report and screenshot here: https://www.mediawiki.org/w/index.php?title=Talk:Flow&workflow=rsw3ybqad0yu3fig Partial copy: If $1 is in the header of a flow post, such as "Parametr $1 translation message not found", a weird bug shows up in watchlists where $1 is replaced with the username block of the user
This seems fixed.
