Not enough fighters spawning in Railjack skirmish missions.

[LordSpudTheMighty]

I have run into this issue a few times now. Occasionally in a Railjack mission not enough fighters will spawn to complete the mission.  When this occurs the only option is to abort. This may be caused by killing the required amount of Crewships before you kill enough fighters but I am unsure.

It helps to check locked locations and kill people there if they've "fallen asleep".
It's much easier to start a mission by shooting fighters.
