Some new stuff:
-> After a few loops, installing the generator and fueling it, I went back to the rover and I can "Move Generator Into Laurion" without a generator in my rover and it has no extra completion time on it. Didn't touch it though.
-> Sure wish I could repair the food replicator at Laurion with the taken power coupler from Talos.
-> I tried a loop with installing the generator at Talos. I'm now at Laurion and have the above "Move Generator Into Laurion" available, with time speed up, even though its fused into my Rover.
