Items, that were equipped on the character before the season, were replaced after the season was ended with items that were equipped on the seasonal character. So all those equipped items (before the season) are lost now (one or few were primal)
Shouldn’t all seasonal items (both equipped and stashed) be sent in the mail?
At the time that you rebirth the character, the items you had equipped are mailed to you. You then have 30 days to claim them. That 30 days starts when you rebirthed the character, not when the season ends.
If you didn’t claim them within 30 days after you rebirthed, those items are gone. Sorry.
You wouldn’t have seen the mail icon while playing your rebirthed Seasonal Character. Only if you switched to a non-Season Character would you have seen the mail icon.
Friendly tip: When you know you’re going to rebirth a non-Season Character, stash their gear and their Followers gear first. If you do that, you won’t have to worry about checking the mail. The gear will already be in your non-Season Shared Stash. Then, you can Rebirth your naked non-Season Character to the new Season.
I have had most of my season 28 gear deleted , never transferred to my non season account. I didnt delete my season characters. Soooo frustrating , blizzard support has been useless , same repetitive answer , items are sent to email in bottom left of screen. Even though I repeatedly told them they have not been emailed to me. Spent so many ours farming, so bs.
