i've been dming dead in thay and found 2 bugs with pre-placed tokens first and arguable minor some room are shorted on tokens or out right missing some monsters mentioned in their entries (no skeletons in the corners of room 87, a missing apprentice in room 32 are the one i've encountered so far) and the other is that all the pre-placed thayan warriors have their hp and as swapped in the tokens (hp showing in the blue circle and ac being in the green) so far this they are the only token i've seen like that and they work fine when dragged on from the journal
