After further discussion with the creators, we cannot restore the items automatically, instead we will need a full list of items to restore. Please include all enchantments, quantities, etc. If you have any questions, let us know.
I don't remember most of what was in my echest. The only thing I do remember is a diamond pick with silk, unb3, mending, and eff5. I don't think anything else that got lost was all that valuable, so if I could just get the pick restored that would be great.
