Dynamic Lighting graphical issues & crashing

Bug 1: Honda Xeno Drivelights Bug 2: The Twilight Zone Bug 3: Hellscape Hello! I am a youth councillor from Finland and I am running Dungeon of the Mad Mage for 15 players, working in 3 seperate parties but sharing a singular world. Dynamic Lighting has been bugging heavily for our game for the past weeks, but during our last game we had a festival of glitches reveal themselves. ALL of the following glitches happened at the same exact time, when I removed a Door line from the Dynamic Lighting layer. Bug 1 - Multiple characters have Torches, Light -spells etc. in use. However, only the Hooded Lantern of a single character is shown to the player, regardless of the other characters being next to him and they all sharing the more or less same vision. Bug 2 - The player sees an area where the coloured light of the pillars mingles with the light of their torchlight as a negative colour for some reason? Some of the light breaking through is still normal. Bug 3 - The player character has their Aura effect turn their surroundings into a hellscape. I can only think of this happening because of their Aura sphere mixing together with different lighting elements and the textures glitching somehow. As a continuation: During the upcoming encounter the players kept having issues. Players were using both Firefox and Google Chrome. While Firefox seemed to be more keen on graphical glitches and issues, lighting on Chrome kept blacking out each time a single figure moved, was added or was removed from the map. As a method I have not yet tested I have thought about separating the characters. Until now all the players have had the ownership of all character tokens for the sake of simplicity, but I'll test on our next game at Wednesday 13.4 what happens if I'll just assign tokens to their rightful players. Could this solve the issue? I have no experience in anything tech-related on this level to recognise what the issue might be. The bugs all happened on Level 6 of Undermountain: Dungeon of the Mad Mage in room 15a. I have added custom lighting to the pillars in the room to reflect what the book says of the lighting of the Quartz pillars. As a Dungeon Master, my game has not had any glitches (I have used Firefox as I've run the game).

Check the Lighting Layer if there are any borders for the pillars. If you place a torch inside a pilar that is framed by such a barrier, no light will go through.

For the glitching colors.... are you using colored lighting and/or colored night vision?  Those seem to be problematic for me, especially the colored light.  You might try removing any tint colors from light sources or night vision, and see if that helps.  I haven't had any problems with regular auras, so you could use auras to add highlight colors to light sources that need them. Sometimes, I get the negative color effect from a light source, and sometimes not.  I'm not sure why it isn't a constant issue, but I can say it only happens for me with tokens that have night vision with the nocturnal effect.  If I use no effect or the dimming effect, then I don't see the negative light bug at all.  If you are using the nocturnal effect, you might see if switching to dimming (or no night vision affect at all) makes the problem go away for you. That might allow you to work around #2 and #3.
