Card Game: Mission receive MORE wound/treason tokens?


In a couple missions that are supposed to receive wound/treason tokens, the player who plays the last token gets the Success rewards. This brought up an interesting question, can a Troubleshooter add MORE tokens than necessary for the mission? And as such, the last player to add any token (as opposed to token #3) is the Successful player.

We played like that last night and it greatly lengthened the mission, since everyone was trying to put a token on, and the Team Leader never completed the mission since she wanted to put one on as well. The mission I think had 17 Traitor Tokens by the time we ended. But, is that correct?
