Let's take some things into consideration, as I observed the round in it's entity.
Conflict during transfer and shuttle is allowed to continue as long as it draws to a close. Seeing as a threat was made that there was a bomb and it was set up, and to your other complaint about the AI's reasoning of calling the shuttle, it was ongoing conflict.
Could a bit more roleplay been involved in the situation? Yes. As I will always tell Nuke Ops, communication is key if a plan does not follow through. But it's also very, very difficult to have communication between AFK players, Dead players, and Lost players, and the amount of ahelps from the team of "Oh, I don't really feel like playing it" or "I'll be AFK, I really can't stay", doesn't do good. If I had the power to put in replacement ghosts, I would, but it was only a few people on and I did not have that power.
In short, the team was messed up, but that's because there was really no teamwork due to a lack of a, well, team.
