Hello there, i'm totally lost, i've never seen this kind of problem before, i'm actually building the version 2 of my personal modpack (V1 can be found here http://www.technicpack.net/modpack/comoys-bigpack.534311 ) so, i updated all mods, adding others ect, (i removed minefactory because there was compatibility problems) so now, my modpack is up to date, and ready to go, no more crashes or problem while loading up, go to minecraft main menu, "nice it works!" But, when i try to generate a new world, it seems to look fine for some minutes but then the computer shutdown itself, i tried several times on different computers, and it's always the same problem If you can help me, that would be really awesome, because i've never seen this before You can download the actual version of my modpack here http://www.technicpack.net/modpack/comoys-bigpack-v2.740305 https://www.dropbox.com/s/wo8ect9umiyebte/modpack.zip?dl=0 Thanks for your help !
