Fixed Stuck at class selection

In-game name:
NoneTaken

Short description:
NPCs to select class don't appear / are invisible

Long description:
Every time I have gotten past the Goblin quest the (I assume) four NPCs to select class don't spawn. I have tried restarting the game, turning off shaders, logging out (& /logout), creating a new character and playing far slower with the dialogue to no avail. It seems like this is a persistent issue regardless of what I try.

I think that the NPCs may actually be invisible and un-interactable rather than not present though as I can hit where their entity would be and hear a hit sound.
