In the airbnb payment tos ;

At 9.2 Airbnb absolves itself paying out if it cannot collect payment from the guest , labelling itself as a Limited Payment Collection Agent to exonerate.
9.2 Each Providing Member agrees that payment made by a Purchasing Member through Airbnb Payments, shall be considered the same as a payment made directly to the Providing Member, and the Providing Member will provide the purchased services to the Purchasing Member in the agreed-upon manner as if the Providing Member has received the payment directly from the Purchasing Member. Each Providing Member agrees that Airbnb Payments may refund the Purchasing Member in accordance with the Airbnb Terms. Each Providing Member understands that Airbnb Payments’ obligation to pay the Providing Member is subject to and conditional upon successful receipt of the associated payments from Purchasing Members. Airbnb Payments guarantees payments to Providing Members only for such amounts that have been successfully received by Airbnb Payments from Purchasing Members in accordance with these Payments Terms. In accepting appointment as the limited payment collection agent of the Providing Member, Airbnb Payments assumes no liability for any acts or omissions of the Providing Member
This particular issue infrequently crops up in the community pages. On the one hand, perhaps if you keep calling the airbnb service centre they might decide to pay as a goodwill gesture.
I understand that airbnb would be exposed to collusion scams if they guaranteed to pay, so from a business perspective it is on balance prudent to have such an exclusion.
Otherwise, it's another thing for all hosts, new and old, to keep in mind and to weigh up when faced for last minute extensions requests whether to accept via airbnb. For extra guests, it's always good practice to confirm number of guests in advance of the booking start date to prevent errors, deliberate or oversights
