I just figured this issue out, I think it may be the same as this person's issue , so I wanted to post to let anyone else know who may have encountered it. I was testing out lighting use Ctrl-L to see my player's views. One player's token could see the entire map as though she had explored the whole thing (grayed out). No other tokens had this issue, and behaved as expected. I reset all the lighting features I could a bunch of times and it kept happening. Finally, I realized that I had added myself (GM) to the "Edited and Controlled By" section in her character sheet, and this was causing the issue! Removing myself from that fixed it, and of course I can still control and edit the character as GM.
