Packet Handling Error - "blueprint:update_entity_data" [NeoForge - 1.21.1 - Dedicated Server Error]

So, was testing out my dedicated server to help figure out and fix any more issues, and recently I've added Environmental to the server. While within a Blossom Forest near spawn, I got this error log on my Client about being unable to accept a packet. Given what I've tested in a Singleplayer World, I am assuming this error is happening due to my Client trying to load a Deer within said Blossom Forest and is unable to receive a packet which is about data for applying the Deer's ResourceLocation Asset.

Blueprint Version: 8.0.6
Environmental Version: 5.0.0

I'm not seeing anything in the log mentioning the Deer stuff and I am also unable to reproduce.. seems like it might be a mod incompatibility. You'll have to test further I fear and try to eliminate mods

Okay, with just Blueprint & Environmental. No issues at all...

However, I got a different disconnect log that moment I've added just performance mods & Abnormal Team's mods onto my modpack. I will test further to see what is going on.

OKAY! Created a new world on my Dedicated Server and removed the Performance mod... I got the "blueprint:update_entity_data" error again... This is only with Abnormal Team's mods.

I guess this'll make it easier for ye' mateys since it is a conflict between ye' own Team's mods... Let me figure out which one now.

Okay, I am pretty sure it's Woodworks doing the problem with Environmental.
