Re: “One or more create a sims items have been removed…”
@RosariaPauloYour removed dependent items for those sims. Meaning, when you put in mods, or custom sims, or CC there were items included that you removed in modifying your cc files.
ALSO: when you download sims, or lots etc, there are often items that are not part of the download and if you did not have them yourself the game will tell you 'removed create a sims items or cc in the case of lots'
THE MOST COMMON cause is not owning packs / kits from EA that have the items included. AKA: Download a sim you wish to use but not having all the packs part of the sim or lot
