Hi. I really like your mod Immersion! Thanks for your work!
But. I kinda found a bug. Or something that crashes my game. I tried Vanilla and had no issue. I instaled Immersion + Carry Capacity (from Copygirl) and crashes in handbook. Scroll down to Carcass and i think is Bloomery next.. there is the spot where it crashes to the desktop.
I have Game version 1.11.11, and Immersion mod 1.0.8. Hope this was helpful.
