Dynamic Lighting restricting field of view even when Limit Field of Vision is turned off - what am I doing wrong?

The title basically says it all. I'm using the Updated Dynamic Lighting to set a scene of an unlit dungeon with a bunch of green fungi giving off light to a radius of 1'. I've got a couple of characters with Night Vision turned on, tinted purple, and out to a range of 60'. I've got Limit Field of Vision turned off because I don't want the players to have to bother with rotating their tokens. Everything was working for awhile with a good 60' radius, and then all of a sudden all of my character tokens automatically started limiting the field of vision when dropped in. Has anyone else experienced this? Pictures below. Settings: Result:

Update (not solved) The problem seems to be tied to the light I've attached to the fungi. I've tried placing them on the map by: - making it a token that sheds dim light for 2 feet, placing that token on the map layer, and copying/pasting a bunch of times - placing the fungi WITHOUT light on the map layer and then creating a different token that sheds dim light for 2 feet which I place on the dynamic lighting layer on top of each section of fungi The problem only appears after I place a certain amount of mushrooms/light. If I delete everything, the character's vision works normally. Then I start placing the mushrooms and the vision works normally  until I hit some critical mass of ambient light, and I'm not sure exactly what that threshold is. Does anyone understand why this might be?

This is a bug with updated dynamic lighting. <a href="https://app.roll20.net/forum/permalink/9023255/" rel="nofollow">https://app.roll20.net/forum/permalink/9023255/</a> Updated Dynamic Lighting is still under active development. I would highly recommend using Legacy Dynamic Lighting until it is retired for your active games.
