Thanks for the info.
Like you, I can't imagine how the CB could have anything to do with this.
If it's just a 24-hour prank, it should be gone in 6-7 hours when UTC clicks over to 23rd January.
If it ends up as a curious artefact of the Monastery, like vroom's extra 1,000,000 XP,
I don't think it really matters that much.
It's only a node Rep: it hasn't affected my XP; it hasn't affected my level, still a Bishop;
and, it's had no effect on my ranking, still 24 in "Saints in our Book".
It will stick around in the Best Nodes' lists; finally disappearing completely this time next year.
