There's about a 4% chance of an anomaly being Unfortunate Genius.
I assume that came from a xml? I believe that for 1.3 but not 1.4. Current game: Mad Map, incredible, 3 Ai, 2 survey (w improved speed), got 1-2/turn (max) and this continued over 7 or 8 turns. Something seems wrong
I did the math from the 1.41 XML, yes. The event may screw with the probabilities a bit though, not checked that.
Chance of Artifact class = 10 in 115
Chance of Finishtechartifact = 25 in 55.
It's a two-roll system. About one in ten anoms can be an artifact, and about 4 in 10 of those artifacts will be Unfortunate Geniuses. There's also another anom under a different class that gives +25% of the tech's value - that is a separate one with the following values:
Chance of class (capsule) 25 in 115
Chance of research capsule = 25 in 50.
So about 1 in 10 anoms will give you a 25% boost in addition to the 1 in 25 that finish the tech automatically.
