My super phunka trade slave wasn't responding to any commands (dock, follow, rts, etc.) and would drift out pushed (no thrusting/braking). This occured after I had given it a benz engine and trade bot (nothing else) and transfered to my engineer, after which I discovered it was behaving as described above.

Eventually I killed the phunk and towed it from sol, but was not able to reproduce the bug... no idea what might have caused this but I thought I'd throw it out there anyway.

Possibly related: If a trade slave is set to guard someone and they log off it will ignore all orders until they log back in.

It seems to possibly be related to slaves running out of elec/0 elec. Still not sure how to reproduce properly. Has anyone else experienced this at all?

I've had dodgy experiences with slaves without a radar. That could be related (note that a radar also requires elec).
