Potentially silly question

@Lucy_Henley I don't think you really have to worry about that. It would be months (if any) of play or perhaps years of play before that vacant lot you used would cause any corruption. And the way to get rid of most corruption in TS2 is to bulldoze any lot (after Sims are moved out) and remove any copy from the bin. The kind of corruption I was speaking about was after a lot had been occupied and Ron Humble and others had already arrived and even then there wouldn't be enough left over data in the game to really do much damage at all, and if there was ever any it would be on the lot which can be bulldozed. I do that sometimes because some of my Sims have the same last name and hard to get the game to accept familyfunds amounts and give it to the first family etc. I have moved Sims back home from college after parents died and ghosts on lot so I don't really see a quick move in and move out would actually cause much corruption. I once used the hood cleaner mod from MTS and I wish I had just lived with some corruption since doing that imploded my game because yes, there was a lot of left over data and 'hidden' Sims on some of my lots but removing all of those etc. with that mod actually did more harm than good in the end.
