(patch 1.20.1.2)
How do I get the AI to accept Invite To Activity?
The AI weighs it (the answer is partly random). Its reasons: Difference in Rank +20, Difference in Rank -20, … Opinion of …, You … the recipient's rival -50, You … the recipient's nemesis -100, You … the recipient's friend +25, You … the recipient's best friend +50, You … the recipient's lover +100, Relevant Traits +25, Relevant Traits +25 and Struggle agenda.
