I don't know if this has anything to do with the inventory editor I was using (Ultimate Inventory) but:
When I load a world with the plasma technology or the void generator those chunks turn into open bottomed sea.
The void generators were producing a whopping 5 EU a pulse and pulsed every 10 seconds supposedly. (I was able to put them all attached to an MFSU using fiber, I could've probably done copper to a batbox with how low those were putting out)
I am using no other add-ons, a clean IC2 jar and relatively clean MC jar (as clean as IC2 allows it to be) and am using AdvGenerators as a .zip, not unzipped and dumped into the IC2 jar (if that makes any difference).
