First, you're posting this on the wrong section



Second, please if you want to put a crash log put it in a spoiler



Third, the that makes you crash is that one of the mods that you are using is registering an ID that have been already registered. You cannot fix this because of 1.7.10, report it to the mod author (Hint: it was one of Gany(')s mods)

sorry new here

This is a common problem and very easy to fix. so i guess its your lucky day. I had this same problem and its

took 30 seconds to fix. Here's your Problem: at the top it says



java.lang.IllegalArgumentException: ID is already registered: 89



If you don't already know what that means, you have two or more objects/items/mobs/biomes/dimensions with the same ID.



For the heads mod its this: I:"Mob ID"=89



Here's how to FIX the problem: If you don't know how to get to your .minecraft folder, go to your start menu and search

%appdata then go to roaming and last your .minecraft folder. Now look for a folder called config. In there there should be a

headcrumbs.cfg file. Click on that and scroll down until you find a part that says: I:"Mob ID"=89



All you have to do is change that to a different number, that's not being used by vanilla MineCraft or any of your mods.

I recommend using a higher number like 300-400 so it won't interfere with vanilla ID's.



And there you go! if you picked an ID that no other mod used it should work. if not, try a higher number or look at your mod IDs and

see what number hasn't been used. Any time you get the



java.lang.IllegalArgumentException: ID is already registered: "number"



error, you can easily fix it. Hope this Helped!

Didn't the 1.7.10 Forge makes it so you can't change the item ID?

Item IDs are now descriptions with mod name first if it belongs to one. But entities still have them.
