Re: how do i make a house hold that i accidentally switch to unplayed playable again
To change a household to played from unplayed, as @Pick-a-boo_doo says, just enter the lot in live mode just like you are going to play. Let the game run for a second or two, then exit the lot. When you get back to map view, you should notice that the color of the household icon over the lot has changed from dark green to a light green or grey. If the household is not on a lot, you have to move them into one first then go to live mode and exit back to map view. After you've got them back to played status, you'll find them under the My Households tab in Manage Households and they'll have a dark green icon in the upper left corner of their Manage Household portrait and a solid heart in the bottom right corner. If you don't want the household on a lot, you can just evict them. Then they will be shown as "Not in World" in Manage Households with a light green icon in the upper left corner.
To do the reverse and change a household to unplayed from played, go to Manage Households and then select the My Households tab. Scroll down until you find the household. Click on the little heart in the bottom right corner below the household portrait. Then the household will be moved to the Other tab in Manage Household and the little heart will be just an outline rather than solid and the plumbbob in the upper left corner of their portrait will be grey.
Hope this helps.
