Le Havre
Does my Person disc move when I take goods from an Offer space, or when a round ends?
Several players agree on this reading of the Main action and disc rules; no official post addresses it directly.
No. Discs only ever go onto buildings, never onto Offer spaces. If you take goods your disc stays where it was and keeps blocking that building for others, as it also does across rounds. It only leaves when you enter another building or the building is bought or sold.
