So FFG has made a great way to resolve what happens in a game if your opponent chooses an illegal red maneuver when they have stress tokens. In tourneys, my opponents have done this twice.
What has happened in tourneys 5 times is that the opponent has placed a dial that does not match a ship type next to a ship. In two of those cases, they chose maneuvers that ship cannot do (Tie Interceptor doing a 1 bank for example). We usually rule that it does the maneuver but adjust the color as necessary or do the closest approximation to that maneuver (2 bank for an interceptor).
Is there an official ruling on this? Its just as likely someone will make this mistake as chose a red with stress. I have caught myself almost making the mistake a few times, wait he doesn't have a white 3 turn...
If there is not an official ruling how do you folks handle it?
