So I was playing Forge 1.16.1 (version 1.16.1-forge 32.0.43) and I died to fall damage. When I went into my mine it had mysteriously closed off the path between 2 stretches of mine. Then when I quit Minecraft and added a few more mods, the world rolled back to a earlier save (I think) and I lost most of my obtained ores and nether portal. Can you help?
