Yup. Fraid it looks like we'll have to split the two squadrons to two separate airfields. 😠
However, on a plus note, after flying a sortie with BluBear managed to get the next day's mission to generate! Logged progression it seems is now acheivable!
Will have to make some further edits and tests regards the new airfield. Thinking A-89 Le Culot might be the best option for the 485th guys.
