Myself and my friends are on Xbox however I’ve seen others with this issue on PC as well.
In short the bug happens when you play with more than 2 players.
If you are in a lobby of 3 or more your friends (excluding host) can’t see each other.
I was playing for about 2 weeks with 1 friend and we had no issues but as soon as we got another player in the game they couldn’t see eachother. One of them couldn’t even see some of the robots we would fight.
I’ve only ever noticed it with 3 total players or more.
We’ve tried everything from switching hosts, resetting our games and even hard resetting.
Nothing seems to be working but it’s becoming a pretty big bummer that we can’t really play together.
