Now this is something unexpected. I was translating the article on Grolier Codex from English Wikipedia to Polish. The CT crashed halfway through (right column greyed out, couldn't edit anything, reported countless times already), so I simply copied over the last two sections (I could click on the left column paras) and published the translation to my sandbox (here).
The refs in the original are in the simplest form possible: <ref> tags, with Oxford style citations typed in by hand (as in <ref>Kowalski 2007, p. 7</ref>). This format is native to MediaWiki and should in theory work on every wiki out there, no matter what. To my utter surprise, it turned out that Content Translation somehow managed to damage the references. Some of the refs were simply deleted while publishing (in this edit I put some of them back in; I also did other stuff in this edit, but you'll get the gist)
was converted to
<div class="cx-overlay"><div class="cx-spinner"><div class="bounce1"></div><div class="bounce2"></div><div class="bounce3"></div></div></div><div class="cx-overlay"><div class="cx-spinner"></div></div>
Lastly, what I missed initially was that some refs were automagically shortened:
<ref>Markenke 2012. Yates 2012. Baudez 2002, p. 3.</ref>
Does anyone have any idea what is wrong?
