Sorry if I'm being a bit ignorant, but what is the current fortnightly topic challenge? According to the topic discussion, the metapuzzle thing ends on May 3rd. In fact, this also suggests that the metapuzzles topic has also ended. Has it?
EXTENDED: Fortnightly Topic Challenge #30: Metapuzzles ended May 3.
No new Fortnightly Topic Challenge has formally begun since then — perhaps due to the current election, but also perhaps because none of the regular FTC maintainers have had occasion to score the challenge just ended or to post the new topic.
I think Lukas Rotter had built some automation to automatically add FTC entries to the relevant page (and maybe to tally up results), but as they are no longer active here I think much of the FTC work is in search of a new champion or two.
