Can the option 'Flee' be individual, and not affect the battle going? It shouldn't really bring bugs in my opinion, since doing so 'was' a bug back then.

You could quit from your party mid-battle and the battle would kick you out. So, just make it so whenever someone that's not the Leader attempts to flee, they'll escape alone.

Or even make this one Trait called 'Cowardice' or 'Lone wolf', idk.
