Teleportation can't really be broken can it? What makes me think it is something I am doing wrong are threads like this one where people ask for teleportation to be added to the GUI - why ask for options on the GUI for a broken feature?
It is also such a "big ticket" feature to lose that I simply have to be doing something wrong.
If it just affects a small-subset of platforms and I happen to have the unlucky combination...well that sucks, but that's life!
And yes, I have read the docs.
