So I had this pop up while I was all the way down South so I go there to hear a few guns fired and the battle ends but the objective remains.

I've waited around for 10 mins another 1 raider came and my turrets killed him.

So I tried travelling elsewhere then it said I failed the objective wtf does it expect me to wait there all day?

Maybe there was still a raider left but he was hidden in the area. Something similar happened to me as well and I found out that one raider got stuck inside a big crate. Sometimes they glitch inside big and solid objects and it's really hard to see or kill them

And the hunt begins... Lol thanks

Found nothing, work so hard and the game just [censored]s you over!

Sorry just want to bump this incase someone has a fix.
