Countdown has a major issue and has had this issue since launch. This is an issue that is not reported on Trello.
Issue: When the final objective is completed and the supply box is made available, at least one player is disconnected from the entire game. This happens almost every match and may consist of multiple disconnects. The player(s) disconnected must exit the game and reconnect - outside of the Countdown.
Edit: Once the disconnect occurs, the player(s) cannot reach the extraction area -- this presents a couple of problems. Now, most of the rewards are with the final Hunters/NPCs, and no points will be rewarded. Lastly, there is no way for the disconnected player to reconnect in the match.
