I think there are two items with the same id.

"java.lang.IllegalArgumentException: [TCon API] Material ID 1020 is already occupied by Invar
at tconstruct.library.TConstructRegistry.addtoolMaterial(TConstructRegistry.java:361)"

Try to go in the config files of Tinker's Construct and change the item with the id 1020 to another that is not used.

do you know where i can do that

In .minecraft folder you'll find a folder named config. In this folder, find the tinker's config file. Something like Tconstruct.cfg. Open it with notepad and find the id 1020. Then change it to an Id that the game is not using (I dont have how to now exactly what id, but try a number up to 3000). If the same crash occurs again, try another id.

I'm playing on 1.7.10 i just updated all of the mods that I was told to. thats whats caused this crashing

I had ever this problem when I updated a modpack. Try to delete the config folder. The game will generate a new, with correct configs to the updated mods.

I cant change the item ids in the config file this is 1.7 shouldnt this not be an issue?
