@Flappie My track files aren't loading correctly, but I will save the track next time it happens. It happened consistenly on PGAW, and I never managed to get off the ground. While taxiing I was cycling waypoints as a sanity check, and to make sure the coordinates were correct. The first thing I noticed was the first digit on the data panel wasn't showing the first digit of the lattitude when cyling between Long and Lat. The other numbers were showing so I could read them, but the first digit was blank as the other ones cycled. I tried to input the coordinates again because I was worried they were incorrect, so I went REFLOLA, INPUT, and started to type the coordinates. This is when the crash happened both times. I will do some experiments and try to reproduce it, but fiddling with the data panel too quickly and whilst moving seems to be the killer for me.
Another issue that may or may not have been flagged is the formation lights on the left wing never turning off, even though the switch is off.
