Things to check: 1) (Regular) Fog of War. If active on that page, make sure you have cleared an area for them to see. The default is for the page to be entirely obscured. You can reveal areas using the reveal tool (looks like an eyeball) on the toolbar. 2) Lighting. Make sure that player tokens have sight , that there is a light source , and that they are linked to a character that is controlled by a given player . Don't assume just because you linked a token to a character that they are still linked to it. Verify on the token that is on the board. Setting the default token must be the last step in setting up a token. Otherwise any changes (like turning on sight) will not be reflected in the token when it is dragged from the journal tab. 3) Test before the game. Control L is a good quick indicator if a token can see something. Giving control of that token to a dummy account and logging in under that account is a surefire method.
