I create some Sims and houses but all the sims and houses were attached with downloads.Lots size was increased so much but when I check it by using Custard Program it shows so many CCs I haven't placed on the house.When I remove them its size reduced for more than 20 MB and also there're lights,blinds,plates,cups even on sims.It happened not only one export but all of them.What can I do to get rid of this problem.Please help..
