I made a modpack with a bunch of mods, with one being hordes, but I disabled infection in the config to make it easier. The issue is the game crashes as soon as a zombie attacks me, probably because the game tries to give me infection even if I disabled it.
Here's the crash log:
The game crashed whilst ticking entity
Error: java.lang.NullPointerException: Cannot invoke "net.minecraftforge.network.simple.SimpleChannel.sendTo(Object, net.minecraft.network.Connection, net.minecraftforge.network.NetworkDirection)" because "net.smileycorp.hordes.infection.network.InfectionPacketHandler.NETWORK_INSTANCE" is null

Sorry, I found out why. I resolved by disabling all things related to infection: the issue was probably related to the game trying to setup some animation or particles even if I disabled the option to infect the player.

Disable infection should completely disable everything, without having to touch any other settings, I will work on fixing that, which version do you get the crash for?
