Hushed up, more likely non event, with the commentator not really across possible operational issues. When you have a flight that goes beyond the validity of TTF forecasts (3 hours) because of its duration, you can run into issues as the 30 hour TAF validity is not exactly allowing for highly accurate forecasts.
If a TTF/TAF suddenly changes to one that requires more holding fuel, it would be prudent to return and put more on. I am guessing that is what likely happened.
