Yes, I also had a problem with Spider Tron 6000. I shot off the head but it kept on shotting.
Good find! That one's called "Remote Control Spidertron" on Asana. A couple people have run into it here on the forums, and I've certainly run into it during testing. It will hopefully get fixed one of these days. ;-)

Oh boy, this is going to be so much fun. Watching this game become a wild fire of fun!
