How do Milestones work, and what counts toward them?
The designer's 2022 ruling on Fairchilds replaced his 2020 comment.
Milestones come from this expansion and are scored with the objectives on the scorepad. They count tiles showing the rose icon only, so hybrid and similar tiles do not count, and any legitimate servant action that meets a requirement is valid. A Fairchild does not count toward the prestige-guest milestone: the designer first said it did (2020), then ruled in 2022 that a Fairchild counts for a prestige guest objective but never for a milestone.
