When I try to place the unconscious Rothwild in his interrogation chair, one of the following happens:

• Rothwild dies immediately as I place him there, making me fail clean hands and making me unable to continue.
• Rothwild just falls over on the floor as if I dropped him, and the objective to place him in the chair fails at the same time, making me unable to continue.

What the actual [censored]?

Google tells me nothing.

This is forcing me to interrogate Abigail Ames instead, which is the wrong way. Not the way I want to go. But your bug is forcing me to.
