Console Errors Flooding (PlayerMoveEvent, NullPointerException and ViaVersion Head Packets) with Build 40 HotFix-1 #296

Closed denniemok closed 3 years ago

denniemok commented 3 years ago

General Info

1) GodsEye version: Build 40 HotFix-1 2) Server Version: Spigot 1.8.8 (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT) 3) ProtocolLib version: 4.5.1, as instructed on GodsEye's Spigot Page.

Problem Description

This problem does not have a significant impact on server performance, just some errors spamming in the console after installing Build 40 Hotfix-1.

PlayerMoveEvent: I'm not sure how to reproduce this issue. It just appears when a few players were pvping, and then at some point, it just started to spam the console.

ViaVersion Head Packets: (this is triggered whenever a player joins the server):

[ViaVersion] Received an head update packet, but there is no head! O_o CompoundTag { {Rot=ByteTag(Rot) { 0 }, x=IntTag(x) { 1204 }, y=IntTag(y) { 4 }, z=IntTag(z) { 325 }, id=StringTag(id) { minecraft:skull }, SkullType=ByteTag(SkullType) { 0 }} }

Thanks.
