Another Sim Town Immortality

If your Sim knows a Sim from the default Party Boat town, Another Sim Town, and you want the game generated Sim to know your Sim’s future grandchild or something, do not worry. The game’s makers made their Sims immortal. They are somehow unaffected by the Life Dreams and Legacies update. For example, my old Sim, Andras, loved a lady in the town. Andras died a very long time ago and his lover is still an adult!
