Your Rally point is wrong, Alpha is the one you need to start at, Bravo is far beyond that point.
• 1:05 - Terminal 3 - Mission 4 'Infinity' - Rally Point Bravo
After meeting up with your teammates, there will be a short cutscene and you will spawn inside a ship. Just turn around and the terminal will be directly behind you.
Edit: NVM I'M JUST DUMB LOL!!
Good thing I went through the whole level instead of just turning around when starting...lmao.
