Hello, I am playing a session and that began weirdly, some players could see the map others not, I brushed it off for the time being but then when I swiched maps the same problem arised, all of my players just saw the white board with squares, so i started checking and could not find what's wrong. I am with fog of war activated and they can only see the area of which I revealed but only the white defaut background, not the map. The map is in the map layer not in another, and they can see all tokens/drawings, only not the background map, and the "orange flag" is in the desired map. Also, when I (the DM) go into player mode I see things as they were supposed to, not just the defaut background We went trying to go to different maps, all with the same problems, and maps of which had worked in past sessions, strangely, the only map that has worked is a map which is in the token layer and has nothing but a map (no fog of war activated). After that I tried to put the maps in the token layer, but also did not work. -I am using roll 20 on Microsoft Edge, but my players use a mix of google Chrome, Opera, and Microsoft Edge, and Chrome with the duck duck go extension. -Other than the previously mentioned, we are not using any roll 20 extensions. -Dynamic Lighting is not turned on If more information is needed I'd lovo to provide and I want to know what is wrong and what should I do Next?
