From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Denery Date: Sun, 6 Nov 2022 02:02:46 +0300 Subject: [PATCH] Fix player kick on shutdown Fix preemptive player kick on a server shutdown. If you update minecraft version / upstream and something is changed in this method make sure that a server doesn't disconnect a player preemptively, also check if all packets are ignored during the shutdown process.
