Ran into an odd issue with Multisite (still exists on current version)...
I'm looking at the login log across all sites in the multisite, and the latest logins are NOT at the top... they're always a few rows down.
We have hundreds of sites on the multisite and I suspect the issues exists because some of them have different timezones.
I believe if the logins list would be sorted by login ID descending, it would always be in order, and I don't think that should have any negative impact.
As always, happy to test. :-)
