Well i Just looked trough my mods and the one who is overwriting og.class is optifine :?
Maybe i should try to install optifine first and then forge ?
EDIT: I did that and it worked but i found another bug...
All custom items doesn't have their item sprite pictures for example : fridge is snowball in my hand but when i place it it's normal.
EDIT 2 : I just realized that custom textures even overwrote original textures and now for example emerald is other item 0_0 that may be bug in the mod it self
