I have a block lag problem that's cropped up over the last few weeks (I'm still on 1.3.0 btw).
At base, no problem. I can take out a spire without a hitch. But, the further away I move (from base) the worse the mining lag gets. At a distance of 1000, after a few minutes the lag kicks in so bad it takes 3-4 tries to remove each block. I also start to get long game freezes (up to 10 seconds) that drive me mad. All of this goes away if I walk back to base. This problem also exists in the Nether.
I've tried restarting the client while away, no help. Ram and CPU stay close to normal (6 core AMD, 8Gb), and the only error on Forge is it can't keep up with ticks.
SO, I suspect a mod for something I use at base. Deleting the chunks for the base solves the problem - but I don't want to start over.
Any hints on what I can do with out destroying everything one block at a time?
