Behind the scenes

 * Vault dwellers in the add-on repeat idle dialogue lines that previously appeared in Fallout Shelter such as, "Who do you think would win in a fight, a lumberjack with tentacle arms or a shark riding a unicycle?"
 * Lead artist Ryan Sears and lead developer Kurt Kuhlmann describe the constructible vault door as a scaled-down 1x3 tiled-version of those seen in Fallout.

Bugs
A bug can occur in the DLC wherein a supply line appears between Vault 88 and another random settlement. The trigger for this is unknown, but it can occur at any point after the initial quest is given, even before gaining access to the Vault 88 workshop.
 * It can be resolved using a Vault-Tec Population Management System in the connected settlement.
