Hi, good that you managed to overcome the situation, in most playthroghs I ran out of h2 in the middle of space so it is a familiar feeling. The autopilot is not a journey planner yet so you have to do manual adjustments since it can have +-1s error and at 10km/s that means 10km error plus forgetting to activate overshoot prevention can lead to dangerous situations. Not to mention a 2degree of-course direction can translate to hundreds of km away if not corrected early.
