Just like in a previous tutorial of mine this will be a short fix for those who are having issues with just those tools in combo with optifine (Texture issues, Major Errors)

Here is a clear cut solution in video step by step on how to work around this glitch by manually installing optifine into your versions folder and also which order to install.
