What plot twist most disappointed you?

[Peelee]

She required a tie with her vote, not counting the lesser deities.
So one pantheon needs to vote yes, one pantheon needs to vote no, and from her pantheon there need to be exactly 9 votes for no. Otherwise her whole plan would have had zero influence on the outcome.

IIRC, the Giant said she didn't get really lucky with her plan, but rather she formulated her plan based on how she calculated the vote would go.
