When the wild was regenerated i lost my house and everything in it. I lived with my cousin and brother who had chests with items in them as did I. Now those chests and everything in them are gone. I and my roommates had many things in those chests, most of which were valuable. I would like to know if there is any way I can get my stuff back.

I had things such as full diamond armor, iron, gold, lapis, building materials, and much more in those chests.
