Hi, I'm having a similar issue myself. The first time that happened was last sunday. That day i decided to assign a default token to all player's character, so that everyone would be able to get a full image portrait as well as a round token i made out of their pic with a token stamp. I first created tokens on the map we were playin in, and evertything was ok. As soon as we moved to another map, i copied all character tokens and pasted in the new one. When i did that, there were three character (out of five) which couldn't actually see their own token, neither some of the others (but the could actually see one player's token and npcs that were already there). It was weird since the other two players could see everything. I found out that removing default token and drag and dropping their character to the map was actually working to make them able to see every token and control their own. I had all the token properties set up correctly, and no dynamic lights nor AFoW. I started to drop character tokens from art library on the map and then assign the tokens to character, without setting those as default on their character sheet, and that apparently worked well. The same thing happened to me these days, i set dynamic lights on new maps, and checked proper settings for every character tokens (assignment, brightness and vision). At first one player (he had the same issue the previous time) couldn't see his token, so i dropped a new one and assigned to him, and that worked. A couple of days later, after i edited all other maps settings for dynamic lights and copyied the "working" character tokens on every single map, that player that presented issues couldn't see any of his tokens again on every map, and I could fix that only by drag and dropping his character on the map. It seems there is some sort of setting the players fails to setup or something I am missing or doing wrong, but i can't figure out what.
