I got the error message:
Error while loading recipe prototype "deadlock-packrecipe-y_rwtechsign" (recipe): Difficult normal:Value outside of range in prototype tree at ROOT.recipe.deadlock-packrecipe-y_rwtechsign.ingredients[1].amount
I seems like a recipe bug but when I disable BigBags Mod, everything run smoothly.
The same crash error will also come out with angel mod.
