https://en.wikipedia.org/w/index.php?title=Matt_Chandler_%28pastor%29&curid=37214846&diff=573675359&oldid=571858677 For some reason, multiple different unnamed references all get name=":3" there.
Isolated test case: https://en.wikipedia.org/wiki/User:Ed_g2s/Sandbox4 Diagnosis: The automatically generated names are based on the number of distinct references in the page up to that point, indexed at zero. The first unnamed <ref> tag is the 4th distinct reference on the page (it's preceded by two :1s, a :3 and a :0), so its autogenerated name is :3. However, there so happens to already be a literal <ref name=":3"> on the page, so we get a naming collision and the whole thing goes to hell. In practice, this situation can only arise after multiple iterations of duplicating unnamed references with VE (which adds <ref name=":n"> tags to the source), then removing or reordering references so the ref tags are aligned exactly right for this bug to occur.

James, I think it can be confusing that the name and the number of a reference do not match, although the links work. See https://en.wikipedia.org/w/index.php?title=User%3AElitre_%28WMF%29%2FSandbox&diff=575128343&oldid=575128003 (the reference #2 gets a ref name:3).
