So this quest just will not work for me, I have been trying to debug this myself for a few hours now, I've tried Ender IO pipes to pump them in making sure its configured right with always on extract and stuff, tried a hopper on top and on the sides and thermal dynamics itemducts but it simply won't accept my dirt. I thought maybe it's being funny/tricky and tried giving myself about 200 quadruple compressed dirt thinking it might want it in that form seeing as you can submit them manually but that didn't work either so I'm at a loss as to what to do. It won't even let me insert the dirt manually using the OSS interface.

Help.

I came here for basically the same issue. (Submitting a fluid instead.) Anyway, the problem went away after I downgraded to BetterQuesting-3.5.320. (Also tested 323, 327, and 329.)
