4) The circumstances of the bug or precise steps to produce it.
When selecting units for a mission, I put out a SPARK. This resulted in a massive infiltration time that exceeded my limit (Limit: 4d1h). I then replaced him with another soldier for a more reasonable time. I then put in the SPARK again, just out of curiosity, and found that it was now well within the time limit for the mission. With two more low-profile soldiers, I was at a mere 4d2h of Infiltration time. For some reason, the SPARK alone has a longer infiltration time than the SPARK with 3 human soldiers.
While I doubt anyone plans to run solo SPARK missions, I suspect something is wrong with displayed infiltration time, one way or the other.
Lastly, if it matters, I have the SPARK relatively early on in the game (I did the towers mission in 1.0, before the mission was moved back).
5) Whether you are able to offer a savegame for us to look at.
I have a savegame available, if needed.
