I’ve edited some words into my previous reply in this thread. Specifically:
If you’re expecting Marks that you earned after the pre-patch went live, and don’t have them, you can hopefully check for them and restore them.
Go here, select ‘In-game Issues’ and then ‘Items and Mail’ to get started.
It’s intended that tokens that were in the mail during pre-patch maintenance on May 18 were purged.
And as others have noted above, Game Masters are not able to restore any Marks.
