About NullPointer Fix for Mio
From ModrinthThis mod safely fixes the null pointer issue in Minecraft network packets.
This mod safely modifies the core read method of Minecraft network packets. Whenever any mod attempts to write null into a packet, the method automatically replaces null with an empty CompoundTag at the return stage, ensuring that any subsequent NBT operations (such as getString, getInt, etc.) will not throw a null pointer exception.
