Character can't see each others Vision on one map, but on another they can.

So i created an Avernus campaign. While the players can see each other's vision on the main map (upper pic), it's not the case for another map, although i got the same settings for adv. fog of war and DL (and also the tokens). I don't know if i am missing something or if it's a bug, but i'd be thankful for any help. Also, everyone has control over every token/player. greetings, chemiQs

push - the problem still exists.

Does your main map have light barriers on the dynamic lighting layer? Because it looks to me, as if the "other characters" on the lower image are blocked by such a barrier from the selected tokens vision. Also, as far as I am aware, characters should only be ably to see their own vision. On the upper image, the selected token is prolly able to see the other characters because they are within FoW range and not blocked by a light barrier.

Yes they have. Makes sense to me - So is there any way to make them see each others' vision with those barriers? Can't remove them for obvious reasons.
