Issue description

I've been playing this modpack for a while and love it. My mekanism multiblocks are right next to each other, 15x15 fission reactor, 15x17 turbine, and a supercritical phase shifter, as well as all the machines needed to make fissile material. My computer was loading all this with minimal lag until yesterday, now if I get close enough to where it tries to load in my frames drop to 0 and stays that way. If I click a button it does it 40sec later, When I eventually teleport away my frames come back and its fine. If you know any way to fix this that would be great. It lags breaking, placing, and opening machine gui's as well even though frames are fine. I have played other worlds before and it works fine. No idea why it just stopped working. I am playing on the Ragnamod modpack and they have identified mekanism as the problem.

Could you please try using spark to create a sampling profile of the game and provide the link of the profile here so we can better see what is potentially causing the lag.

Haha set spark interval to 30sec, ran into lag area and came out with this....

So took a quick look at it. Seems like its not mekanism pipes but pipez gas pipes?
and....... hoppers?

Not sure why those are causing lag because there is maybe 5 since I started swapping them out for mekanism pipes. I am a bit hesitant to delete the mod and reload since other types of pipes from Pipez is scattered around.

Looks like the vast majority of the lag is being caused by Extended Crafting, it is probably worth reporting to them.
