Everytime I move for a bit, my client crashes and this message pops up: The game crashed whilst unexpected error
Error: java.lang.NoSuchMethodError: net.minecraft.client.multiplayer.WorldClient.isPlayerUpdate()Z
I am running the game in the latest forge for 1.12.2 and the mods I have installed worked before I updated to 1.12.2 from 1.12.1. How do I fix this? (besides going back to 1.12.1 as some of the mods I want to use require 1.12.2)
Had a similar issue. Everything worked fine on .2 though so I assume it is because one of the mods I updated today. Here are the logs, though I doubt they have any useful information.
By the way, I saw someone assuming it is because of Optifine since it never works across MC Versions. Seems like a .2 version got released so updating it should fix the crashes (assuming this is the reason for them)
