So i got the quest from Panther about the courier who should have the data disk. Then when i get to the top of the railway bridge where im supposed to go, there was a message from Panther:
Hey, Soldier! You’re in the right place,you should be able to see him from there without being spotted. Get the guy's flash drive, but dont harm him if you can help it.
But he wasnt anywhere near the bridge to be found. I tried waiting for him a bit but he still didnt come. I saw in the walktrough that im supposed to get message like this after the previous one :
Kuznetsov. I'm here, with the data you requested. I need those photos. If you don't have them, then the deal's off. You have until I reach the southern outpost...
But i didnt get any message like this, only the one from the Panther
