My girlfriend is trying to join my LAN world, we both have the same mods and versions.
Whenever she tries to join, she gets to "loading terrain" and then it switches to "saving world" and crashes, giving the following error.
"The game crashed whilst unexpected errorError: java.lang.NullPointerException: Registry Object not present: cofh_core:chilled"
Crash report - Crash log
Any help is appreciated!
