This is Smooth Motive Drop (Makes key motives like Hunger drop smoothly instead of changing speed depending on their current level, like in Sims 2) updated for 1.5 / University. It does NOT affect PlantSims, and may be updated to, depending on whether or not they're stupid.
WARNING: NPCs in Dorms are apparently complete idiots, and sometimes will not feed themselves. They die of hunger. A lot. I recommend always SERVING meals and "Call household to meal" every time you eat, because it looks like they've got something wrong with their AI. This mod does not afford them the 24+ hours of time to figure it out that the default game does.
