You can get to NP 0 through a temporal rift way before you get Signpost. (I did this from NP 300 or so, obviously it only works if you don't have Safety Net yet.) If you do that, the message it gives you isn't helpful or true ("Only absconding to the edge of Time will avail you now.") The only way to get out is ACTUALLY to use a Temporal Rift.
I don't necessarily think the message should be changed, but I do think that Free Advice should have advice for a player who's at NP 0 and who doesn't have Signpost. Perhaps even explaining that Temporal Rifts are much more common when castles are finite, would be appropriate in that weird case.
