Hello everyone! Im hosting my own server on my home server on version 1.21.5. On Startup, Cave-Ins were not enabled, and i went to fix that. however, even after enabling Cave ins, rock instability wont show up, and no cave ins occur. i tried: using the command "/worldconfig CaveIns on" and restarting the server manually changing the "serverconfig.json" file (screenshot attached) and still, no cave-ins. please help!
