Base Defense Trouble

I been having troubles with my Base Defense, its acting like I haven’t done the mission known as “Good news” and I dunno how to fix it, regularly I just go to a different server with random ppl and use theres but it’s the fact u dunno what’s wrong with mine. It’s got a whole Machine Defense tower around it where u place the C4 to get access to the Base Defense. If anyone has any suggestions plz let me know. I’m on Xbox and my gt is AggroElysium
