I personally would like to see Dynamic Lights - Cosmetic - Minecraft Mods - Curse Added to the MyM launcher. I personally add to all my packs and the great thing about it is its client side. What this mod does is make Torches emit light when held or thrown on the ground. It also make Gold armor glow, its like a mining suit.
Since when are you using it and around how many times have you played with it? (We tested it in the past and it caused quite some issues.)
I have always used it. Its one of my must have mods. What issues are you running into? Since 1.6.4 I also use to use MAtmos, cant seem to find an updated version
Mainly light update bugs and performance. I guess we can give it a shot but I would say as non recommended (player needs to tick it to be enabled).
