Hello. I noticed that when you're in Nether, breaking netherrack will lag, in the form of appearing and disappearing again once its mined. This only happens in Nether, I tried it the normal world - no lag there. I have checked all my plugins that is related to this. Breaking blocks in nether that is not netherrack, it does not lag! Video: I did a CPU test, but nothing there... I also tried to disable spawning and difficulty. No differance.
