We at Wiki Project Med are working to relaunch our translation efforts. The problems of ContentTranslation dropping references; however, still persists.
Here was the source content being [[https://en.wikipedia.org/w/index.php?oldid=1022115153|translated]] and here was the target content that resulted. https://ja.wikipedia.org/w/index.php?title=%E8%A1%80%E6%B8%85%E7%97%85&oldid=83393053 Here is the edit restoring all the missing / dropped references. https://ja.wikipedia.org/w/index.php?title=%E8%A1%80%E6%B8%85%E7%97%85&type=revision&diff=83393098&oldid=83393085
I previously believed that the issue occurred when the full definition of the reference occurred within the infobox so we had a bot move the full definitions out of the infobox for all our leads that are ready to translate. Yet the problems persists.
A more precise description, added by @amire80: I've tried to translate https://en.wikipedia.org/w/index.php?oldid=1022115153 to Japanese. Three footnote appear at the bottom, albeit with some error messages. However, some footnote numbers don't appear in the [[ https://ja.wikipedia.org/w/index.php?title=%E5%88%A9%E7%94%A8%E8%80%85:Amire80/Serum_sickness&action=edit | published translation ]], for example the "Stat2020" reference in the beginning of the first paragraph. I do see it while I'm translating, but not in the published page.
