Re: Cross-progression overwritten to lower level.
Hey @miren_tsukiyami.
Apologies for the concern with this situation. Looking over what happened here however, I'm afraid this is not a bug.
Your progress is stored at the EA account level, not on individual platforms like PlayStation or Steam. If you unlink a platform from the EA account and link it to a different account, that progress does not transfer. It looks like that is what happened in this case.
Your PSN account was linked to this EA account shortly after our Cross Progression announcement last year, which means that the progress you made there was on a different EA account. That cannot be merged or transferred from one EA account to another, so if you're trying to restore that progress you will need to re-link your PSN account to the prior EA account.
We have some additional information about this particular situation in our blog and guides below, but if you have any issues re-linking your accounts please reach back out to support so they can help get your PSN account back to its original EA account.
