I was doing missions for the career agent Jieken Jenpen. It started off normal. The first one was to deliver a package. Then I got to do some salvaging. I got a Venture ship. Then oddly, even though he was not he industry agent, he told me to mine and get 333 units of Tritanium, which I found odd because this was the business ageent not the industry agent. I did the mission and it looked like my next mission he was going to shoe me something useful to do with the Tritanium. I was like cool, the rewards of that one seem pretty good but I got to take a break. When I came back to login again, the mission Balaencing the Books 5 out of 10 appeared to change from doing something with the Tritanium to delivering a data chip. While this is more logical, I wonder what happened to the other mission, because that looked more interesting and now it seems to be gone.
