[Bug]: Pose Stack Error

[fluffybunni5]

Pose Stack Not Empty Error

Hello! I'm using Ice and Fire via the Medieval Minecraft Modpack for 1.16.5 (thru ATLauncher) but I keep having this issue where when a stage 4 dragon is destroying lots of blocks, I get a pose stack error and crash. This has happened twice without being able to relog back into the world to fix it in game. The first time, it fixed itself without me doing anything, but this time nothing I've tried has worked. The devs of the modpack told me to come here for help.

this happens when mods don't properly handle the pose stack or work on it cross-method

(e.g. push in a pre render event and pop in a post event - now what happens if a mod cancels only one of those)

there is no sane way to debug this and it's unlikely to be caused by this mod
