ok thanks i'll use the coal but i probably won't be building anything with it for a while because stuff i build around the quarry where the atrium to plan has a tendency to dissapear, including torches that i've layed out and also the library.
also is there any chance of recovering the ~12 stacks of netherbrick, 2 stacks of red wool, 2 stacks of blue wool, and 1.5 stacks of dirt i used to build the library? also the books placed in the chests there have dissapeared though i guess you can't replace the writing in them so nevermind about those.
