That's pretty much all that does happen and how it's been for many versions now. You should be able to interact with them same way an enemy and lead them around to whatever you want to make them do and they don't resist (other than trying to escape there bonds if left alone) They will also try and help other slaves/you get untied if possible.Is it just me, or does saving captured enemies in stationary devices not work in 0.7.0.1? Upon loading a save, the characters just appear next to the device.
