Students on the Translation Studies MSc course at the University of Edinburgh are translating articles using Content Translation. User:Sariputrahan is trying to translate the Chinese Wikipedia article on the Tianjin Grand Theater into English Wikipedia but User:Maxliu1993 accidentally began to translate the article in her Content Translation tool.
Maxliu1993 has since been translating a different article to allow Sariputrahan to translate the Tianjin Grand Theater article BUT it is still showing the warning that she is still working with it:
"This is an ongoing translation by Maxliu1993.
Please make sure you coordinate with the user who translated the current translation."
Maxliu1993 has discarded this aborted translation (as pictured) so then Sariputrahan should be able begin but anyone who tries to begin it gets the same error above (pictured).
