Auto-spawner needs mob essence, cursed earth gets you a bunch of different things, and powered spawners require a crazy amount of power for any sort of decent
Mek 5x is nice, but certain aluminum's don't work with it. I know IE's Bauxite only seems to work with the Enrichment chamber. Might work with the pulverizer.
Also, incase anyone is using IC2 for anything, instead of burning bronze on it's wrench, I suggest using the Prototype Omni Wrench from the Modular Powersuits Power Fist. It functions like an IC2 wrench, and will also manipulate Railcraft tracks like a crowbar. Doesn't link carts I don't think but I spend way more bar working on the tracks than anything else.
Anyone know how to make Nutrient Distillation? It's not the normal recipe, and there doesn't seem to be one. I've 'acquired' it, but can't make it fair. I'm using the remote inventory panel so I can get to my sludge boiler product without getting poisoned.
