Glitch: Sometimes the fathers of toddlers will appear on the lot without ever leaving again. Sims are unable to ask them to leave or say goodbye to them and they can move through doors set to only allow household members.

for the glitch above you can also go click on the sim press more click actions and add to group then there will be the option to ask them to leave
