My Quarry works perfectly with direct contact, not sure what's going on here.

Hey there! I just built a nice nuclear power plant, housing 5 Mark-I reactors in one building. It's not that efficient, but it refills itself with uranium and has loads of power. However, there's a problem with it: Whenever it's running, moving away from it causes my fps to reduce drastically and according to the debug monitor "Tick" suddenly uses 80-90% of my ressources! It only happens when I was close to it before (close enough to hear the sound). And it stops when I get back right next to it again. Please help me fix this since I don't want to stay in my power plant all day! D: Client Version is 3.0.3, Server is 3.0.4
