When launching a craft with the 'Space Laboratory' carreer attachment the mission states it is assigned to another craft. When pressing the 'refresh' button, the missions simply fails.
I have used this exact rocket setup for multiple other Space Port Esperanza contracts, but only this specific mission has had this issue.
Manually assigning the mission part to the correct contract also did not fix it.
There are no other craft (aside from the space port itself) active.
