Oh my, "cobble gen madness" is aptly named. I set up 128 Igneous Extruders... and I'm tempted to add another 128. It's a mark of some quests' difficulty that the resources I spent for those Extruders are insignificant compared to what I need for, say, "Magnetic Personality". I'm also using my newly-acquired 16M storage to store jungle leaves. Currently at 400K after only a few hours which will get me 50k dirt of the 600K I need. Maybe I won't need another Ender quarry run.
BTW, can anyone tell me if there is ab bigger dirt collection quest after the one that needs 100 quadruple-compressed dirt? Because by the percentage shown, there appear to be some invisible quests in the For the Hoarding section and the only unfinished quests I can see are the one for purple things (waiting for my sheep to make enough wool) and dirt collection.
