Strange... I had no problems splitting the teleporters up between characters, giving both to either character or leaving one or both behind.
Some people have also had problems combining the bomb ingredients in the DK's inventory, though the mixture should just be put in the hero's inventory.
I asked about the Raanaar because when I did that quest the one I needed to talk to wandered a bit away from the others, and I didn't see him at first. If none of them acknowledge the fixed teleporter, that is a bug.
