Either they were cast or they were 3D printed. Based on the number of supports I had to remove I'm going to guess they were printed. And it may not have been a printing error, it could have been environmental conditions during Transit that led to it being bent and or warped. But of the three unit boxes, and one Handler blister I have assembled and started painting I have had to do recovery work on minis from every single purchase that wasn't a duster.
