Sometimes when I ask about topics that the characters should know, there is no reply (the text on the screen doesn't change, even to the default 'I don't know' type of message). It always occurs while asking about important things (eg. Pyrn about the teleporter) I can't remember other situations, but there were quite a few of them. Up to now, was I sort lucky, because the 'rest' of the world acted like the character told me that info, but now I'm stuck.
Help!!
