Very often interactions between Zois are very cumbersome, because the Zoi we want to interact with already has automatic actions queued up.
In the video, for example, Seung wants to have a romantic conversation with Julius, but he keeps getting distracted to drink, listen to music, watch TV, etc. It all becomes very boring. If the other character is playable, it gets resolved as I did in the video, but if it’s an NPC many interactions go nowhere.
Then I had to remove the beverage dispenser because the Zois who frequented the place would just drink continuously 
.
Another problem is that Zois who are in a location because it’s programmed by the Schedule often wander away for various reasons: interactions with Zois very far away, sometimes to give a snack to a cat they walk for a long time. They should stay where they’re supposed to be.
In the video you can also see the umpteenth Zoi who at 9 PM still has their backpack on their shoulders 
(sorry for the delay at the beginning of the video).
