Okay, so we have fixed the problem and it should be available again to those that have it with the following gotchas:
You need to restart the game client and log back in to see it. You should no longer have to make the trash character and buy it, it will just be unlocked and ready.
If you purchased a lifetime subscription in the last 24 hours your account hasn't been fixed. You can either put in a ticket so we manually fix your account or just wait 24 hours and it will be automatically fixed.
