Hi, I am attempting to set up my server with Forge Mod Loader and a few mods, I have already placed Forge Mod Loader and the mods in, the mods being GUI API(in coremods), Custom Mob Spawners, NEI(installed correctly), Damage Indicators, Mo' creatures, Industrial Craft 2, NEI red power plugin, the redpower packages, all of them, thaumcraft, and twilight fores, but whenever I attempt to start up my server it crashes, something about a Exception in server tick loop

*blink blink* Does it help that I don't actually make mods? I'm kinda stupid about putting this together, I got the clientside working perfectly, it's just the server that I'm no good at...

Wait sorry I put the wrong awnser. Let me try to make a server using those mods ok?

I think the problems is Mo' Creatures. If you want the server to work. You have to delete Mo' Creatures, Gui API, and Custom Spawners.

GuiAPI only goes in the client coremods folder.
