As the title suggests, my skill bar has been completely frozen, but it is a little more interesting than some related posts to this bug.
This bug happened after killing the boss at the Werlyn Docks in the ruined era. Once I killed it, I teleported out. I noticed that my wolves appeared desummoned, but I was not able to summon them back. I found out that ALL of my skills were unusable. To make it worse, I can’t change them to any other skills.
Now the most interesting part, my skills ONLY work at the Werlyn Docks in the ruined era. When I teleport back, my wolves are summoned and waiting for me in that area… What!?(lol) I can use the skills in that one zone, but I still can’t change them. The bug persists after dying, restarting the game, and verifying files. I even kiled the boss again(the quest refuses to complete even when I pick up the chest). I also tried to walk out of the area entrance rather than teleporting, nothing helped. Removed all of my gear too and that was not the issue. The character is effectively bricked. The silver lining is that it is only lvl15, so little time lost.
Here is a link to the video. I hope the info provided helps.
