This mod prevents certain Sims from leaving jars with caught butter- or fireflies, and comes in two versions:

• everyone – prevents everyone from leaving jars;
• nonFamily – prevents unselectable Sims from leaving jars. Members of a currently played household don't leave jars only when they're within hotel grounds, on a community lot (like in the unmodded game), or on a secret lot (except for secret societies).

A jar that isn't allowed to be left on a lot is placed in the inventory of its owner, if they're a member of a currently played household (not a roommate). In other cases it disappears.
Use only one version at a time.
