I wanted to start translation of [[https://simple.wikipedia.org/wiki/Uber|Uber]] from **Simple English** to Serbian in production through gray interlanguage links, and **English** article was loaded.
Also, I tried finding Simple English articles which don't exist in English Wikipedia.
- [[https://simple.wikipedia.org/wiki/Thirumanam_(TV_series)|Thirumanam (TV series)]]: Even though this article exists only in Simple English Wikipedia and not in English Wikipedia, it gets loaded with `from=en&to=sr` in the URL. Not really clear to me where the source content is coming from, but it differs from Simple English Wikipedia article.
- [[https://simple.wikipedia.org/wiki/Radha_Krishn|Radha Krishn]]: Article fails to load with "Critical error: Content translation failed to load due to internal error" message displayed in infobar below the publish button toolbar.
- [[https://simple.wikipedia.org/wiki/Brown_v._Board_of_Education_II|Brown v. Board of Education II]]: same as above.
