There was a discontinued plugin that was amaznig it cleared the world of loose blocks laying around causing issues. And it did a check each 2min or 5min depending on what the admin set it to. I now have this old issue where my server is sometimes lagging bacause of to many loose blocks laying around aparently some 50k-80k blocks not "disappearing" on their own getting stuck somehow. But unfortunally the original "Autoclear 1.2" is discontinued so i was hoping someone could make a new one. - Should be able to set time interval between checks - Should clear the world of loose blocks at the interval
