So recently we migrated our server to another host since the previous one was uncooperative. They refused to send us the world file so I had to use the World Downloader mod to get the world. That worked great to get the terrain and buildings and all that, but chests have to be saved manually by right-clicking on them while downloading. Now I would like to add chests belonging to certain chunks to my newly downloaded save, but downloading the specific region files and replacing the existing ones in the new server ruined the chunks around them, somehow.
I've tried using NBTExplorer by searching the word "chest" in the world folder but it doesn't find anything relevant.
