ISSUE DESCRIPTION
Description of the issue:
As screenshot shows, after cca half of flight time the FOB doesn’t change compared to Fuel used value.
FREQUENCY OF ISSUE
How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every time.

I like A400, but the fuel bug makes longer flights not realistic, so I have added a way to sync fuel on the plane to Simbrief plan in my jumper tool, i.e. fuel will be set to a distance based average from two adjacent waypoints in the plan. Sync is NOT continuous, you need to click a button to do it. Works fine as a temporary fix. There is a way just to sync, no need to use jump function. One thing I am not sure about is the order to use tanks - the plane only uses FEED1 and FEED4, I don’t think it is right, so I programmed CENTER first, then L INR/R INR, then FEED1-4 proportionally. From my understanding FEED1-4 always feed engines, but are kept topped up from CENTER and L/R INR if those have fuel. I still like the plane very much 
I do some checks now as,
especially fuel used values FU from display to see if I have some free fuel still, compared my set FOB/block fuel value. Due this very bad bug it is really hard to simulate something now, as you also conirmed.
