Flexa node (Railjack-Veil) not working as intended

[Galantys]

So I 've been playing Railjack solo lately, and I wanted to play the assassination mission in grineer veil proxima, the only problem is that the assassination part is not working.

Once I enter the mission I have to kill the enemies and destroy the missile platform, but the grineer galleon does not spawn ant killing the general is not an objective, so once I destroy the platform the mission completes itself.

Thing is, I want to play the assassination part too and it's not happening, and I want to do it in veil proxima 'cause I want the spectra vandal. I would like to know when this bug is fixed because it's affecting the short time I have to play.
