Not quite the same. This issue is specifically with the TBM where it always spawns with 0% fuel. The issue you quoted is one with all aircraft where they spawn with 38-46% fuel and you cannot change it.
I believe the other issue is a career thing, because no-one (as far as I’m aware) is able to actually select their fuel prior to starting a mission and have it replicate into the actual sim when you start. It always defaults to ~46%.
This TBM issue has (as far as I’m aware) only been experienced with the TBM, and it’s consistent across all flights where you will always spawn with 0% fuel. The fact that the bugfix solution is to fly the TBM once in freeflight, then go back into career makes me think that it’s an issue specifically with the TBM and how it’s being managed in the career mode.
