There's a portal you can take that leads to Limbo and the card says to move there immediately without spending any TU. That's fine and makes sense but there's another portal that you find in the Chamberlain's house (I *think* that was his title) that you can use if you have Rohm with you. That portal does not specifically say that using it does not cost TU.
We've played it twice using that route and spent the TU both times to do it, but we're starting to feel that that is wrong. After all, it's just a portal and you simply step through it. Why would this portal work differently than the one to Limbo? Does anybody else feel that this is an oversight and the card SHOULD say that it costs no TU to use?
