What to do? Is it a bug?

Hi i am playing game on hardest difficulty and I am stuck. Game is just not progressing. All I do is defending Havens and killing Citadels. But I cant do anymore story missions. I am at that part where You got two places to search ancient ruins. The one I did was not the propper one and the second one I failed to do on first try. Problem is I cant try again because when I am at that site all I cant do is scan area but cant deploy again because deploy button is gray. Or am I missing something?

Have you tried flying away and imitatively coming back?
You probably already tried that, but I thought I’d mention it.
