On 22 October 2020, BlackWidowMovie0000Editor was blocked from editing Moviepedia (found at https://moviepedia.miraheze.org) for 17 days(https://moviepedia.miraheze.org/wiki/Special:Redirect/logid/4134). This should have expired on November 8, 2020.
Instead, the block is currently to expire on 28 October 2021 (https://moviepedia.miraheze.org/wiki/Special:BlockList/BlackWidowMovie0000Editor). That's not right.
What's worse is that the user was unblocked, three times somehow, but still remains blocked. The notice with the latest entry even denotes the unblock:
I've been told by Dmehus that this is likely to be a bug in Miraheze extensions and not in MediaWiki itself, and may have been caused by the update to 1.35.
