LookAt AimOffset in the Anim Graph causes character to explode

LookAt AimOffset in the Anim Graph causes character to explode.

I hadn't used this node yet, but it seems new to 4.14.

1. Download the attached project
2. Open the AnimBP found in the Test_AimOffset folder
3. Select the LookAt Aim Offset node in the graph
4. Assign the Aim Offset from that same folder
5. Compile

Result: Character explodes. I don't know how else to explain it. See Screenshot.
Expected: Character uses the AimOffset with the given inputs.
