As we might have noticed, gregtech 6 interactive blocks like machines or mortars or even crucibles have gray mining particles when mined. I though of a potential fix.
Maybe remove the mining particles from machines alltogether? Since you aren’t “mining” the machine, but instead picking it up with the right tools removing the breaking particles could be a good idea.
Up to greg to decide and this isn’t gamechanging, it’s just me subconciousnes cringing a bit while “mining” machines with white particles…
edit: as a side note, waila harvestability lies sometimes. I hovered over a burning box with a pickaxe and it said harvestible (when it isn’t) and on the other hand, hovering the burning box with a wrench says it is NOT harvestible, when it is.
