Re: is there anybody at DICE i can talk to about an issue or bug in the game?

What @xxxC🤭lBr33zExxx says. It's like this:

Express Train:
2 assist ribbons and 10 kills inside the Metro must be achieved within the same round.

Dead Stop:

You must raise/lower Caspian gate and get a shotgun ribbon in the same round.

Now, about Big Splash, it's a more problematic one... about flood gates from Sunken Dragon, which gametype did you try to activate them on? CQ Large or something else? Also, aside from that, did you try to get kills while swimming already?

Also, unfortunately I don't think that contacting a dev will be possible... devs are not present on AHQ. In the past the best way was participating in CTE subreddit, but CTE is pretty much over now, so it will not work.

dead stop i did that in a round...got the shotgun kills but far as the gate...didnt show as completed, but alright

Whenever multiple requirements have 'In a round' part in their description, it means that they must be done in the same round. It's not described in the clearest way possible, but that's how it works.
