Game crashes after NPC shoots

[ABBI?? 0]

Hi there. I am experiencing an issue with the Custom NPCs mod. When I give an NPC a gun and set them to attack mobs, upon shooting the mob the game crashes and I cannot enter the world again. My screen has also started acting weird after experiencing this crash. I tried to get the crash log with vanillafix, but it failed. Help ?

The guns are from Flans mod btw

I'm having the same problem, every time it doesn't matter what guns they are it just is what they shoot make it an arrow and it will work. I have no clue why anything else breaks it but it doesn't help me either sorry for a not good response please contact my email if you find a fix before me. AdeptTurmoil@gamil.com
