I am DMing for a party of 5. I have dynamic lighting turned on and working perfectly for everyone. Everyone except one player. That one player has vision of everything. He does not have GM privelages, he only has possession of his token, and the vision on his token is set up correctly. We have determined that it's only not working on his end. It doesn't work for him on any map or even in his own campaigns. It worked for him fine two weeks ago. He is using windows 10, google Chrome, and Windows Defender. These are the same features as my machine and as one of my other players. Does anyone have any idea what could be the problem?
