I had a double chest with all my saplings, acorns, and resin and half the chest disappeared, and ALL of the contents are gone!
Are you sure there was no creeper explosion, fire spread or anyting that could destroy the chest on this modpack? Like i member on one modpack Goats could ram the IC2 machines and many people was making doze of threads about missing machines.
I thought that too, but the remaining chest wouldn't be empty, and there's no fire, lava, or places to spawn on half-slabs. if there were a creeper, or fire, or any of that, my floor is entirely wood.....
I've already moved on, replaced or remade the missing items, etc. Just wanted to be sure it was notated. Here is where the chest was missing from: x= 1787 z= (-768) y= 64
