Exactly what Hosfac just said.
Crinrict has a preliminary post on their blog about the problem and how to handle it, although it is subject to change as more information becomes available through further testing.
http://sims3.crinrict.com/en/2012/03/simport-sending-sims-and-custom-content.htmlThis definitely gives me pause, but does not put me completely off this game feature. I am going to create a separate folder where I will allow SimPorting (for the time being, at least) - I won't allow SimPorting from the folder where I run my important games. That way if something does happen I won't lose anything of value to me.
I only have members of this forum as friends, and I trust you to take appropriate measures to avoid transmitting CC. If I don't know you that well or have seen CC in your stories on the forum I will come right out and ask you about the sim you want to send over. Please don't be offended by the question and please feel free to ask me about my sims before hosting them. For the record, the only things I have other than store items are some patterns from the Exchange and our own Swap Shop.
(Note: I'm not against CC - there is a lot of really great stuff out there and I have used it in the past. It's just that I already have more stuff from the store and our Swap Shop than I know what to do with and I don't want to bog down my game with more stuff.)
I hope this won't completely deter people from SimPorting. I think it has a lot of potential as long as we are careful and considerate of each other.
