I recently created a new world in this modpack v8.01. what happens is that every time i put a turtle from computercraft to mine (btw its a mining turtle) it mines like half the blocks and leaves the other ones there. i found out that these blocks aren't even real, i tried to mine them with my pick but apperantly they are already inside the turtle. i also tried the excavate command and its even worse it leaves a bunch of blocks..... ive been trying to fix it but ive had no such luck. and btw i have optifine HD U D1 i dont know if maybe this mod is causing some graphical glitches but its very annoying. Plz help me Thank you
