426 hour game no longer loads

My first time playing 7 days. Only world I have. I have been blessed to not have any major glitches until now. Base disappeared along with truck and drone. I fall through the map if I walk where my base was and now the game won’t even load in unless I just mess with all my settings to the extreme. And eventually it glitches back out. A little discouraged and not sure if I’ll play any more but it was my happy place bashing zombies and looting pois.
