steam linked your EA account no longer have access to steam account

Hey @yPmm,

Is there any way that you can reach out to Steam support to try to get access to your Steam account again?

That seems like the easiest and best way to solve your issue at the moment. If you can get access to it again, then you don't have to worry about lost content and the like.
