I’m having this issue on console as well. Actions cancel out in favour of autonomous greetings and general conversational actions following the greeting.
It even takes several cues for my sim to merely introduce herself to another. As soon as she reaches the target, the action cancels.
On several occasions, it can take minutes for my directed command to even drop down and register. “Reset object” doesn’t work for this issue.
There have also been times when I direct my sim to go talk to someone wandering around the neighbourhood, and the target sim keeps walking (or jogging) away- won’t stop to allow my sim to reach them. The action only cancels once the target sim has disappeared. My sim will chase them up until that point.
My experience is very similar to
