Fred is bugged since some time ago.
Seen some additional 3ish reports that I didn't add to the post due to laziness/lack of response to the issue.
LRing fixes it afaik.
So I did an LR to fix the feat issue - what a mistake.
Adventure compendium: wiped. Looks like I'll have to reflag for every raid.
Destiny XP: wiped.
Favour rewards: wiped. No yugo pots for me.
I'm close to giving up, this just isn't worth it.
Sorry this is no help with your issue. But I thought I would post that I submitted a ticket about this a few months ago and even a Game Master was unable to help me. I eventually True Reincarnated. I've attached the screenshots I took, but there really isn't any additional information:
The only feat Fred is allowing to swap is Wild Shape. Im level 13 and it's as if I have no feats at all.
Seems to be same problem on my TR1 - unable to swap PBS or HE Dilettante: Cleric. I took Toughness at level 2.
