On two occasions, we were stuck on the dialogue wheel with none of the speech options being clickable. This is just in the first 3 chapters already. With one we went back to the graphic settings and changed it from "full screen -windowed" to "full screen." When we restarted from the last save point the same dialogue wheel options were clickable. The second time, we again made a change, this time to windowed I believe and restarted. While that worked, I am not convinced what exactly is fixing the problem. Is it changing the windows setting, just exiting and returning to the game, starting from the last checkpoint or what.
The point is there is clearly some kind of maybe random bug where the dialogue window locks up and no option can be selected, preventing the player from progressing.
Both times were at the mansion, once with the police officer and once with Silas.
