Okay so I've got a dreadnought design with a Kingfisher module. I've designed and built a Patrol BR, and both DN and BRs show up in th ebattle rider manager. However I can't actually load the BRs. I can drag the BR names around, and there's two slots that show up on the DN, but if I try to drag and drop a BR to the slot, nothing happens. Is this a bug, or am I doing something wrong?
