Ive noticed that about 75% of the time when I start my engines in the default LJ45, that upon hitting the left or right START switch, the engine will start spooling and show an increase in N1 value, but then jump back to zero, even though N2 is showing a continuous climb as well as the engine sound climbing as normal too. Sometimes though, it wont do this at all and it's all perfect.
Really getting anoying though- has anyone else seen this or know of a fix?
