Thanks. Looking into this issue further it seems the content is just incomplete and pending additions. I've made some changes for the next release that should hopefully address these issues (at least partially).
For the after-party invites, the portion with the zaibatsu-specific invites will be cut out (so just ignore it for now). Adjatha just completed writing the proper post-party event that would eventually be an invite received by mail instead of in-person. I am unsure if this event will be coded before the next release, but it is pending to be implemented soon.
And for the slyveren ambassador, I've made it so it should now track your character's response on the subject of slavery. At the moment, there isn't any alternate scenes written for when she approaches your character post-party, so I left it unchanged. If and when there is alternate material written, the scene should parse properly based on that response.
