So I ended up staying up all night and debugging the IC2 issue on the test server after all. The issue is cauldron is deleting a public variable. They know the issue and are currently working on a fix.
I know who is loading chunks or not via other methods other than the allowed ones, so this is a warning, if i see a random quarry down somewhere not working at all, I'm going Pherce. If you like the server like most of you say, dont abuse it, help it
