I was running a game and when one of my players joined they had GM view, they had not been given GM access by accident as they were still a player after checking. The player had access to the GM layer and they could see through the dynamic lighting, I assume they had been given GM view. The other six players in the game had not been affected and had their standard player view. After the player rejoined the game their view had gone back to the player view. Has anyone else experienced this and is this a known issue?
