Compatibility issue with custom NPC

[Zack7292]

im trying to run a simply modpack (only tools mods that i keep to test things around, including custom npc for the diemsnion teleporter) and after running it with your mod, i got thee following crash: https://mclo.gs/awpXrFO after turning on and off mods, i found out that this mod was causing it, tbh i have no real idea what is causing it since it is happening during the 2nd phase of lunching the game, i have retried the crash without any other mods :
