Fixed - Expedition upgrade "Sensors" doesn't work properly.

[Phayte]

At level 10, this upgrade gives a 20% chance for increased returns. I've been keeping track since maxing Sensors, and in 155 total expeditions I have only had 7 with increased returns (4.5%). Even when only counting successful expeditions, that leaves 113, or 6.2%, nowhere near what it should be.

I'm aware my sample size isn't huge, but the roughly 5% has been fairly consistent since I started tracking:
5 in 90 (5.5%)
6 in 114 (5.2%)
7 in 155 (4.5%)

I feel my sample size is large enough to discount 'unlucky' as an explanation.
