link a spell in chat with the title mod and u get this crash java.lang.ClassCastException: net.minecraft.nbt.NBTTagString cannot be cast to net.minecraft.nbt.NBTTagIntArray at net.minecraft.nbt.NBTTagCompound.func_74759_k(NBTTagCompound.java:245) at am2.spell.SpellUtils.getShapeGroupParts(SpellUtils.java:466) at am2.spell.SpellUtils.constructSpellStack(SpellUtils.java:540) at am2.items.SpellBase.func_77624_a(SpellBase.java:115) at net.minecraft.item.ItemStack.func_82840_a(ItemStack.java:525) at net.minecraft.client.gui.GuiScreen.func_146285_a(GuiScreen.java:104) at Details: Tag type found: STRING Tag type expected: INT[] Tag name: ShapeGroup_0
tell them to not do that then, no way around it without poking into ars magika's code and breaking everything as all spells are NBT based
There was a issue like this on AS2 with tinkers items. there is nothing that can be done as Chugga said. Dont link or look at them.
