While doing some analysis, I found a strange inconsistency.

The ServerSideAccountCreation https://meta.wikimedia.org/wiki/Schema:ServerSideAccountCreation event logs show a user with the ID *26048397* and the name *Dhava2nd* being created on the English Wikipedia at 2015-08-20 01:38:57. (Those logs do *not *record autocreations).

However, that user ID doesn't exist in `enwiki.users`. The user Dhava2nd does exist https://en.wikipedia.org/wiki/Special:Contributions/Dhava2nd, but with the user ID *26048409 *(twelve numbers later) and a registration date of 2015-08-20 01:41:07 (two minutes later). Special:Log says that https://en.wikipedia.org/wiki/Special:Log/Dhava2nd that the enwiki account was autocreated, but the centralauth database says the enwiki account was the initial creation, and that occurred at 2015-08-20 01:38:59.

In my cohort, this was the first user out of about 80,000 to have a problem like this.

Does anyone know what's going on? Is this issue documented anywhere?
