Hello, i opened the debug file once i loaded a test world for my pack, but the file was being written new lines indefinitely, i closed the world and then i saw 53k lines with the same message:

[main/DEBUG] [FML]: Attempted to find the oreIDs for an unregistered object (1xitem.lantern@0). This won't work very well.

i have really no idea what might be causing this.

Thanks in advance.

Versions
JustEnoughIDs-1.0.2-16
Forge Mod Loader version 14.23.4.2756 for Minecraft 1.12.2

So what mod adds this "lantern"?

Seems like it's trying to look up if an ItemStack is in an oredictionary while only Items (as in, the type of the ItemStack) can be in an oredictionary.

sorry for the delay, i was pretty busy today irl, it took my nearly 2 hours to find the mod causing it, AdventurePack, which has a lantern i disabled in the config.

Thanks for the help.
