have you angered any reality bending gods lately?
but in all seriousness. I'd suggest you relog and see if that solves things. That seems to be the way you play the game now.
it got even worse after relog ...
I flew away and landed on another carrier and when arriving near it, I had to chase it for like 5 min before reaching it to land ...
my top speed is 420 and without boost I couldn't catch it ...
I know this, but the thing is I was able to request landing, got past it (like 200m) then missed the landing pad and had to chase it after, didn't notice the moving of the FC soon enough to anticipate the landing speed ...Oh yes, if you are in normal space and not in the station influence then it will indeed move away, in this case it appears you were still in the FC area of influence until you got close enough to the station for it to swap to the station area of influence. Objects in orbit are not stationary, they all move at different rates.
