I know this thread is ancient, but that's when I managed to start Dishonored 2. Reloading the save helped, by the way. I like the design of the in-game crossbow a lot. I am a crossbow enthusiast in real life, so I can tell. As a matter of fact, I would like to have someone make a replica for me. The only thing I am not sure about is how much such a custom-made weapon would cost me. Given the best crossbows for their money cost you can find on https://archerytopic.com/best-crossbow/, I would feel very comfortable paying anywhere around 2k.
