By changing my online id will i lose progress on the sims 4?

Hi @MermaidCPs 

You posted on the FIFA forums. I've gone ahead and moved it over to the Sims 4 boards.

According to this list issued by PSN the Sims 4 falls under the category of "Games with no known issues" when changing your online ID: https://www.playstation.com/en-us/support/account/games-tested-online-id-change/#no-issue

I think you should be good to go but best for a Sims expert to confirm.
