Hey Raynen,
The community comes through again.
Thank you, I followed the steps and when launching the game the space was blank, so I replaced the files with the original and relaunched the game and now I can see the MCAS MIRARMAR challenge.
I don’t know if it was forcing some kind of refresh by removing and replacing that section, or if it something else triggered it (convenient timing), but now it works!
Thanks again
