Caves Bug

So I was playing on a solo server on DST as I normally would, I was a few days in, 10 or 11 and then I tried entering a cave, first of all, a black screen showed, and then it said ''Something Awry Went Wrong While Connecting. Please Try Again.'' And then, it was like that for every single one of my worlds? My friend has the same issue, but no-one else seems to, I have uninstalled all my mods, restarted my wi-fi, restarted my machine & restarted DST yet it still doesn't work, I'd really like some help as I enjoy this game a lot and wan't to play with caves, thanks ever so much.
