Controls not working in offline campaign

[Roblex]

I spend 95% of my time in multiplayer but this morning I tried the offline campaign and found it unplayable because it kept ignoring my inputs. I would climb out on full throttle the when I tried to throttle back it would ignore me. Even when after a minutes cursing it agreed to throttle back I found it impossible to land because it would ignore my request to lower the undercarriage or flaps. If I circled a few times until it agreed to lower the gear I would then find it would not completely shut the throttle once I was down so I had to convince it to raise the gear again to make it stop!

Is this a known problem? I fly daily online with no problems.
