[1.7.10] Very weird glitch using Moving Object Position and getMouseOver

Well some time ago i wanted to improve my 3x3 pickaxe. People said to use MovingObjectPosition and Minecraft.getMinecraft().objectMouseOver

 

I did that and it worked perfectly. Now after some testing to make sure everything is ok i found out a weird glitch happening sometimes when i mine from the side. It's hard to describe it with words so i made this video

Here is what happens: https://www.youtube.com/watch?v=UQz2evR9Pck&feature=youtu.be

 

Here is my pickaxe code:

 

package net.aop.items;

I am very confused because i don't know what to do. One of my thoughts is that the ray is going through and it doesn't know in which direction it should mine so it does that weird thing. However i am not sure if i can fix it.

    Minecraft.getMinecraft() is client side only. You cannot use that on the server.

     

    What do you recommend using for the MovingObjectPosition value?

    Yes i know that the copy-paste thing would slow down minecraft a lot but that was the first thing that came in my mind. As for the others, i am going to give it a try and post the results.
