Discrepancy in "Towers of Midnight"

In WoT 13, Towers of Midnight, Tam is with Perrin and Rand at the same time. He goes to Rand, talks with him. At the same time, it is told him speaking with Perrin and crew. No mention of him being taken from Perrin's side by Aes Sedai. Because then Perrin would know all about what was happening in Tear from the Aes Sedai. No mention of Tam coming back either. It says Rand sent Tam back to Two Rivers.
