I messed up and planted to many money tree's forgetting that they auto harvest whenever anyone leaves the lot, even when the kid go's to school. I am giving it away, put it in a safe, spent it, and recycling it in the recycler, lol. I still have an infinite number problem. 999.999.99 same in the household inventory. I have to remember to put those suckers in inventory today. I never had problems with money in the game without cheats or mods so I never really question where money comes from. I will have to start paying more attention.
