Was this a custom created vector field or one from the engine? If it was custom created, where was the world origin of the VF? It looks like your World Origin of the imported Vector Field is not at the center of the field.
Ah that was exactly it, Eric. Thanks so much! It was the only one bundled in the starter content, but I just exported a fresh one in Maya and the issue was gone. “VelocityGrid60” was the one I was using from the bundled content.
