maybe they made their decision while they were still active
I highly doubt it, Bowie has been on throughout the entire day and would've posted it soon after they made their decision.
I think they made their decision a little bit before Bowie posted that they had made their decision, plus Bowie did say "I can confirm the Sages have now made their decision". "Now" Implying they did it recently.
And I'm pretty sure all Sages should be online when making this decision, which fits for you, Tensu and Toadsworthy.
However Tensu believes we should be sus of Toads, which in my book means he is either throwing Toad under the bus or he's being a genuine townie.
