When I tried to load my save file to launch a server, I got a notice that said that my save had a bad zip file. I decided to just make another map to play on for the time being, but when I came back later, the new map was also corrupted. The auto saves are also corrupted. I changed my version back to 0.15.3 to see if that fixed it, but it did not. I have the maps attached in Dropbox links. There are also steam links to screenshots of the notices I got.

Your save files are corrupt - the zips themselves are reporting CRC values when I try to extract them.

That indicates either you've got bad RAM, your hard drive is failing, or you have some software that's corrupting the files.
