I sadly dont know what KCauldron screws up with it. The whole System of placing GT6 Blocks is very complicated and not really something that any external Code should ever mess with at all, considering it’s already almost impossible to make it work with vanilla Minecraft without hackery.
And I cant just use the “normal” way because then we would run out of Block IDs.
So unless I get much more details on what exactly is happening, I cannot really help. : /
