Gray screen flickering

[Silta]

Hi, to keep it short and simple I'm playing a modpack a friend made. However I keep getting a gray screen flickering whenever fighting a feralisk spider. I tried looking at the error log report to figure out what exactly is causing the game to bug out but I don't understand it. If someone could read the bottom of this github report and help me out I'd appreciate it!

TL;DR
Whenever my pawns fight a feralisk the spider AI breaks, does nothing, and cannot be killed while my pawns try to kill it and on top of that the screen flickers consistently.

Gray screen is usually a sign of removing mods. It's basically an error at the very very start of rendering operation which fails and so it stops everything else from rendering.
