Auras are something different entirely. Colored light and vision can quickly lead to display issues when they overlap. Can you explain what you are expecting when you want them to "see each other"? Are the characters unobstructed by intervening barriers? Are they emitting light? Do all characters have vision? If a token is emitting or standing in light, any token with sight and an unobstructed line of sight should be able to see them. Also verify that the tokens, as placed on the board (verify!) , are associated with characters and that players have control over these respective characters. If this is not working for you, a series of screen shots might help demonstrate the issue.
