'Medusa's Call' objective wont load
So ive been making my way through some of the story missions after doing loads of random side quests and Im on the Medusa's Call mission.
The one where you have to kill three radio operators stealthily, gather their intel and then use their radio room.
I manage to kill the 3 operators, loot their bodies and take out the guards without getting spotted but I cant access the radio room. I can find it but the objective marker doesn't update to let me interact with the radio room door.
Ive looked up some of the walkthrough videos and after they loot the final radio operator, the objective updates but not on mine.
I think its a glitch. I've tried restarting the missions several times and collecting the loot in a certain order but nothing works.
I was wondering if anyone else has had this issue?
I think my only option is to restart the game. I know its only an early on story mission but ive put in a couple of dozen hours on the crafting and side missions that I dont want to lose and im not even sure if restarting will even work.
Any help is much appreciated.
