Strange thing.
All of a sudden I can't use my teleporter. I have one in my inventory, and the other in another place (where I've teleported to many times before). I click on the special skills tab, and I have no option at all with the teleporter.
I go to the other teleporter, and switch them out. Well, now I only have the option to drop the teleporter..
Is this a bug or is this how the game is supposed to be?
