ok I know it sound stupid but why the leaves in the trees that I make disappear ? And can we stop that ?
Did you place the leaves by hand or did they generate automatically (by placing a sapling or through terrain generation)? If they generated automatically, then it's vanilla behavior. You can disable block updates for leaves in pocketmine.yml to completely stop them from disappearing. Code: chunk-ticking: disable-block-ticking: - 18 - 161
