The last untranslated message is missing
Fragment of a discussion from Support/LiquidThreads
This sometimes happens because there is an optional message needing update, but I've checked the box under the three dots next to the "Translated" tab and nothing comes up. I'm not sure then...
According to the db it would be this one: https://translatewiki.net/w/i.php?title=Special:Translate&group=int-web&language=sv&filter=%21translated&action=translate&optional=1
Neat! Thank you so much!

When I encounter this bug on Commons, I can usually fix it by opening the last message I translated, add and remove a space (which enables the Save button even though no changes have been made) and then saving.
