From 9ad769150f4bf29a9d6a44dc58f533e961d094e5 Mon Sep 17 00:00:00 2001 From: Shane Freeder Date: Mon, 21 Oct 2024 00:02:00 +0100 Subject: [PATCH] Always send Banner patterns to the client (#11506) The mojang client will not remove patterns from a Banner when none are sent inside of an update packet, given that this is not an expected flow for them, this is not all too surprising. So, we shall resort to always sending the patterns over the network for update packets.
