There are a few bugs in the mission difficulty multiplier for the galaxy contracts (encryptions). First when you change it a few of the fields don't update properly leaving something like this:
The man without head has been seen, find him and blow his mind out. You will get NaN segments from me. And believe me, they are clean
I also have this 2 x Nonlinear Circuit for you if you can do this for me.
Estimated enemy fleet power: NaN
Contract time: 11 turns
edit: second part of bug is not actually broken - apologies
