Removed all my mods and the dev mode works OK, well kind off, I am not sure if I am doing something wrong, I am used to the stable build so may have got into bad habits but I cannot shut down back to cold and dark, usually just shutting the engines down turning of fuel pump, turning batteries off, APU off, fuel pumps off and external power off if connected that works in the stable build but its like there is something still supplying power. Also having a problem with managed speed mode, it keeps making me overspeed with flaps down, is it me doing something wrong or a bug?
