Why is that marked as a “solution”? I still get only the one scientific mission over and over again. That does not make sense, specialization or not. If there are no more scientific missions, MSFS should bring up none at all.
So I want to ask everyone who reads this: Do you have more scientific missions? If yes, then what prerequisites were necessary for you to get them?
And, please, whoever marked the problem as solved: unmark it. It’s not solved.
