Horse Hockey....
Granted, Kill Stacking and Scan Stacking Were Exploits... Fixed!
You can no longer count a Kill or Scan, Across Multiple Missions... Done
Rhea was never an Exploit...
They Nerfed the Payouts and Available Mission Count with 2.4. (For Whine's Sake)
And Nerfed It some More with 2.4.2... (Reasons)
Now go find a new Dead System (Horse) to Beat if you please...
