[OPEN] Scenario: 'Power Couple' get divorced if one travels to another lot

I am not sure if this should be posted here or in the general discussion section...but anyway, onto the point of this post:

I am currently playing the Power couple scenario, but it seem like whenever my one of my sims goes to another lot while the other stays home suddenly the scenario is prematurly completed. I think it considers them divorced all because the wife took the dog to the veterinarian. So, is this supposed to happen or is it a bug/glitch issue?
