Oh My Goods!
In Longsdale in Revolt, must a hired assistant be placed at a production building right away, or can you set it aside?
Place it right away. Longsdale follows the base rule, which requires placing a hired assistant at one of your production buildings at once. The designer once allowed setting an assistant aside, but a 2020 player reply disputes that for this expansion, so the immediate-placement reading is the better-supported one.
