Fresh out of session now, during the session one player who's using firefox said that the map suddenly lit up and he could see the whole map. It happened when he moved and even when he didn't do anything. Other players couldn't see anything other than what they were supposed to and me changing vision for that player didn't fix anything. Moving the players from the map to a different map and then back to the original map made the player who was seeing the whole map receive an error or just get stuck in the loading screen. Are there other people with this problem?
