Its honestly not your fault. you didnt know this would happen.There are reports that when a person puts an IC2 pump next to a compressor it can crash the server. I believe this is one of the reasons why some people ban IC2 pumps. There have been reports about it. Seems that that is what is casuing it. Causes ticking entititys whatever that is. Looks like Nick when he gets some sleep will need to remove the compressor and IC2 pump from your base and hopefully it will fix the problem.
