Huge lag spikes on extractor update

[Nyntex]

Describe the bug

So, i tried to make a gold farm in the Nether with Zombie Pigmans. While I'm in the Nether there are really no problems, but as soon as you leave the Nether the internal server of my singleplayer world starts spiking into 500 ms every second. The reason is probably that the pipes are loading the chunks in the Nether every second (i used tier 4 extractors) and unloads them afterwards. I checked multiple mods and this one is definitly the issue.

How can we reproduce this bug or crash?

1. Place Extractor in the Nether onto a chest
2. Get out of the Nether and check the lagometer

For me it's the opposite. My farms are in the overworld and as soon as I enter the nether it takes half a million year for things to register. But yeah the issue itself is the same for me. This also happens when I go exploring far away from my farms.
