Atc not working properly after loading flight

I loaded a flight flight where I was going from VGHS to EGLL on a 787, the flight loaded at my crushing altitude of FL400 and I managed to turn my autopilot systems on too. But the atc seems to be broken, when asking for vectors to the next way point, it just tells me to basically make a 180 and descend down 3,100 ft. And it doesn’t tell me to change frequencies.
