Yeah, its there and has been functioning correctly ever since the system was put in.
I haven't brought my ox to east or central, because I haven't needed to, and I'm guessing its going to cause a problem if I do. I also haven't tried to unstable my ox on east (not sure if the stable boy's even there anymore) because I was guessing that would screw stuff up too.
So yeah, its fine as long as I keep it on west, as for what would happen if I tried to do any of the stuff listed above.... no idea, didn't want to potentially cause a problem since I hadn't had a need anyway.
