Added prosperity chunks as a possible drop when putting gravel into sifter using iron or diamond mesh. Item wasn't originally compatible with ex nihilo and is needed to create magic seeds.
Added Builder's Bags mod - it's like builders wands but with an inventory! It's compatible with chisels and can auto craft items as well as long as you have the right amount of materials.
Note: I will be adding more items into the ex nihilo sieving drops if deemed necessary. so far everything you need for progression can be obtained by mob drops, loot bags or sieving.
