We are using BiomeBundle v4.1 containing terraincontrol-forge-2.8.2-1.10.2-B1 and
the seed we used was:
7652080513991633117 , the chunk containing the reason for the crash is 2,-56 (just multiply the numbers by 16 to get tp coordinates)

I'm sorry for babying you or anything but:
please just check for Chicken chunks yourself in the crash, i'm sorry this excersice in futility was too much
we just wasted 3 hours tracking down what caused this crash and figured out it was chicken chunks

I'm sorry if i miss anything I am just so fucking done
