I was running Dash Rendar w/ Kyle Katarn and Push the Limit. The Outrider had 1 stress token at the beginning of the movement phase, i revealed a green maneuver and lost my stress token after successfully performing the move, i then lost my stress token and due to Kyle Katarn got a Focus token. Using the Push the Limit i then did two barrel roles giving me a stress token. During the attack phase the outrider spent a focus token to modify a die roll. At this point my opponent told me that "A stressed ship ((cannot execute)) red maneuvers or ((perform actions))." Saying that because i was stressed i could not spend the focus token. I tried explaining that there is a difference between taking an action to get a token and spending the token, but he tells me that the distinction is not made anywhere in the rules.
Can someone please clarify this situation? It is rather confusing and we both can't come to an agreement on what is right and wrong here.
