Minecraft Version: 1.12.2
Ancient Warfare 2 version: 2.7.0.1038
Forge Version: 14.23.5.2859

Expected behavior: Ancient warfare 2 loads
Current Behaviour: Ancient warfare 2 crashing. This happens when I get to the Ancient Warfare NPC's part of the loading process, I have the newest version of codechickenlib installed.

After a while, I figured out my problem. My PC storage was completely packed, removing some games allowed it to run fine.
