I think I may have run into a gamebreaking bug. I am playing D:OS EE build v2.0.99.113 on PC via steam.
I wanted to see what the henchmen are like so I could take them into account when building my party. Therefore, I started a new game and rushed to the hall of heroes. When I talked to the henchman merchant, he told me he would show me the available characters. A single henchman appears... and then nothing. I can't talk to or highlight the merchant or henchman.
This is the first time I got here so I'm not sure how this is supposed to play out, but I assume he lines up all the available henchmen and allows you to inspect and purchase them. Am I doing something wrong or did the game break? Reloading an earlier save doesn't fix it.

EDIT: Started a completely new game but still ran into the same problem.
EDIT2: Deleted all saves, verified game cache with steam, uninstalled, reinstalled, started a new game. Same problem.
