NOTE: T53731#2151432 (and secondarily T63353#2202206, T56579#2151653) were the main issues. The main fix is 052bd7d93, included in the REL1_27 branch or higher and in the 2016.04 tag or higher. **Please upgrade to [[https://www.mediawiki.org/wiki/MediaWiki_Language_Extension_Bundle#Release_notes_and_downloads|MLEB 2016.04 or higher]] to fix issues with updates to translation pages**.
Example: saving this unit: https://meta.wikimedia.org/w/index.php?title=Translations:FDC_portal/CentralNotice2013-2/2/es&oldid=5347994 ("Comenta cuatro ...") caused this simultaneous edit in the translated page as usual: https://meta.wikimedia.org/w/index.php?diff=5347995&oldid=5347984 (see also the matching edit summary: 'Created page with "Comenta cuatro ...'), which however only changed the preceding unit ("Ayuda al Comité de ...", see diff).
The problem is particularly severe when saving the translation of the last unit, because the translation page will remain incomplete even though the translator has actually provided translations of the entire text.
Example: After https://meta.wikimedia.org/w/index.php?diff=5326458&oldid=5326448 (the most recent edit to that page at the time of filing this bug), the page remained at "98% complete" status and the very last paragraph is still in English ("Wikimedia Sweden has started ..."), even though the translation is at https://meta.wikimedia.org/wiki/Translations:Wikimedia_Highlights,_February_2013/61/da ("Wikimedia Sverige har indledt ..."); this misled me to into not distributing that translation to the corresponding communities yet because I erroneously assumed that the translator was not done yet.
Purging the cache (e.g. https://meta.wikimedia.org/w/index.php?title=Wikimedia_Highlights,_February_2013/da&action=purge ) did not have an effect in resolving the situation (the last unit still displays the English original instead of the existing translation).
