It's a cache issue. It pops up every now and then, but at the moment more often than before. I've had it plenty of times, multiple times today even. I've reported it in the past.

As you can say, there's no way to tell if and when this happens. The only solutions are mop-ups after the fact. A null edit - edit and save without changes - or a purge with ?action=purge at the end of the url.

The problem with random problems is they're tricky to replicate - and that's one of the most important steps to fixing it on the back end of Wikia.
