We removed NEI,but something still requires it.
I replaced it with TMI temporarily,for me it at least lets into the Main-menu,but for my friend TMI just crashes the game.
Without NEI trying to connect to the server says Fatally missing Blocks and Items.
Try removing Galacticraft,Galacticraft Planets and micdoodle core.
That I think should fix it,but that way you don't have Galacticraft.If it doesn't,I don't know.
You need to download the galacticraft core from micdoodle8's site.
Galacticraft Planets:
Micdoodle8 Core:
Both of them are needed for galacticraft to run properly,though the planets is not needed to be able to play it.
Edit: lol,I gave a thanks to the guy by accident
I am hosting a server for me and my friends but it seems to be crashing when we join the server,however the map works just fine when I join in SP.
All the mods are the same,latest forge,no config conflicts,everything seems to be okay,however it doesn't seem to work.
Mod List:
Edit 1:Grammatical errors.
Edit 2:Added mod list so you don't have to check the crash-log for what mods I got.
