Kushan Multi-Gun Corvettes

Hey folks, this -may- be a bug, or just an edit to the campaign, but I never had the chance to research multi-gun corvettes… anyone else encounter this?

I read it here somewhere if u have lost your research vessels in an attack while that multi gun corvette research was offered but you had no active research vessels at that time then that it might slip you away. As it wasn’t properly unlocked in your research tree at the time.

If that was the case then you’ve got your answer. In that case it is a bug if no then I don’t know and it might be an even worse bug.

Yes, I also do not have the ability to make multigun corvettes, and I am on mission 13.

There is a reply there that states the research option was in mission 7. But I never got it.
