I did the account merge right now since I have a PC, PS, and Xbox account. I did PC to Xbox first, but when I went to add PS, no progress transferred. I didn't know this would happen, and if I did, I would have done it the other way around. I thought it would change to which had the higher progress, but it didn't let me. I just lost 8MR and all my quest progress. I don't even want to see what else just got ruined.
