Problem

• I click on the portrait of one of my Sims/Pets but the old one stays selected as well. Also all infos stay on the old Sim/Pet
• I click on the portrait but while the portrait itself chances the info stay on the old Sim/Pet

Cause

Like many issues with the interface, this is not an actual bug but the symptom of one. While trying to change the portrait an error occurs that bounces the interface and the old portrait does not get unselected because of it.

Since Pet this issue is happening a lot and it seems it has something to do with horses

Solution

Restarting your game (yes, you can save but preferably under a new name) helps getting rid of the multi-selection in most cases but it can happen again any time.
