Awesome! You are right, it is purposefully a bit slow and becomes sort of a grind to test out your theories of which virtues will achieve a mission. The biggest challenge is the RNG of the +s and -s, but if you go in with 2 possible missions in mind, one for positive virtues and one for negatives, then you should be able to achieve one of them by being able to adapt to the +s and -s that you get. Thanks for playing! Good luck on your next attempt, and hopefully I'll have found that lingering bug and update it before you try again.
