While playing with controller on PC, the “Respond to Social Request” keybind, which cannot be changed as the LEFT D-PAD binding, does not work for me. I always have to use my mouse to interact with a party invitation or request.
Also when visiting a Purveyor of Curiosities Vendor, after pressing RIGHT BUMPER to switch to my Character Panel, I am then unable to use LEFT BUMPER to switch back to the Vendor Panel.
I am unaware if other players experience these specific issues, but I encourage other players to also list their PC Controller issues here.
