There is an oddity we encountered during development of the ElectionBot that might or might not be by-design. Normally, elections are numbered sequentially, and thus we assumed this is a reliable method of enumerating past elections. However, in the instance of elections on English Language & Usage it unexpectedly turned out that the 5th election is missing (whereas the most recent election is #6, and the previous one is #4).
See it for yourself, try accessing the 5th election URL, or take a look below if you are reading this during an active election there (as the
/election endpoint redirects to the election page during active elections):
I've tried to get clarifications from ELU users, moderators, and even a CM, but nobody seems to know what this is about. The biggest point of concern here is whether the sequential nature of election ids can be relied upon, and this is just a fluke, or if it should be expected that it might happen for any site of the network.
I am also curious about the details on what lead to the missing election (there is nothing on the ELU Meta as well) if that information can be disclosed.
As an aside, the title is intentionally punny, and there is no offence meant
