Hi Ernst See the UDL thread, this has been an issue for quite some time, as a DM if you have 3 tokens with night vision that are close then the grid is completely obscured. Players with 2 or more tokens experience the same thing. There was a post yesterday (?) where a Roll20 staff member indicates they are taking out the "sharpen" effect (I think!! ooh, no, Feeblemind...) as this will fix other issues, one of which is the grid loss. Unless of course I have completely misinterpreted their post. Page 13 of the thread, near the bottom Had my first look at nocturnal just now and am loving it though. There are bugs with UDL to be sure, but it is getting there. Thanks Roll20; sending socially distanced hugs n virtual ice cream and a big thanks for the subscription news too, appreciate the 2 year delay, nice touch.
