In 1.12 Jarrod no longer introduces you to the Ambassador twice if you choose to agree with him, but if you are "too flustered" then the narration is still unchanged.
Also, it seems that it's impossible to leak Lisle's secret if you find it out by Lisle telling you on his week 3 date or by spying on the Woodly conversation in week 6. The game is calling a check on lisle_truth, which is only set true if you find it out during the post Penny date Lisle convo in week 5.
Currently, it's impossible to actually get the "paint the map red" achievement. Since the revaire rebel bad ending and revaire royal bad ending don't count as "badends", the game doesn't think you manage to make everyone war each other.
A small thing that bothers me: on Jarrod's rejection scene, how does he magically know that we chose political marriage or observer path? It is not like MM will announce MC's choice to the whole summit if she doesn't get together with one of the main ROs.
