Unable to select combat or utility curios for Brann, therefore unable to complete the quest ‘Delve into the Earth’. No restarting nor log attempts have corrected the issue.
Edited to add: I don’t remember whether or not curios were warband wide before I took a several month hiatus. It was simply that my character didn’t have any curios. I went into the delve and was able to complete it, then got a curio in the rewards, and was able to set one of them. Figured I’d add this info since I’ve seen tens of these issues with no other resolution.
