They should want to plot, but they don't

[Menocchio]

Characters with like 5 + vs 3 - don't want to be part of the plot.
The tooltip tha appears hovering over the Send under the no has everything with it's green asterisc, but the last one. Which says: X character will not accept your offer.

The Intriges window says there are four threats, but I can only see one.

Freedom of will, is what i roleplay
Otherwise it doesn't make sense.
