Screw up game balance and fix bugs by creating more bugs. Now you too can join the discussion. This is where the magic happens. Sometimes actual magic.
So one thought I've had relating to this - Altering records should probably be non kosher, all things considered. But having a separate, add-on section that's only editable by station staff and carries over between rounds that displays with the character-written records might not be a terrible idea? It could be used to make amendments and such. I realize it's not a perfect idea, but it's a thought.
Or I could just add a confirmation when you edit your own flavor text. "Is this what you want your new flavor text to be? It will be saved at round end." If yes, then go ahead and save your changes. If no, then obviously, don't.
Other players editing your record is not going to be a thing though.
