Seemingly the only way to hide enemies in a room players can't see due to lighting is to put those tokens on the GM layer. If they're on the token layer the enemy is invisible but their tooltip can be seen readily by just mousing over the invisible token. This being the case, you can't really let the lighting system do its full intended job because you are forced to hide tokens on the GM layer and reveal them or let players accidentally discover there's an enemy in a section of the map they've never been to before. I tried making sure visibility/edit was off for the status bar, even disabled aura editing, made sure it's associated with a character not in their journal that they can't control. None of it worked.
