Every now and then I'll receive that prompt and get the terms and conditions that have to be accepted. I already did this migration and it looks like my stuff moved to Steam, I even unlinked my Battle.net account and it reflects that on my profile. It looks like I can do the migration again, but it's saying I would lose my Steam characters - but it thinks my "Battle.net characters" it'll replace it with are exactly what I have on Steam now, including the DLCs I've purchased. What gives? Can I dismiss this prompt now? Or am I gonna wake up one day with my characters wiped because I did the migration wrong somehow?
