I discovered what causes the issue, the issue with the Molten Lands quest is because there is not a inventory slot empty, and since the inventory slot checking comes after the mod gets the items from the quest, it causes a bug and leaves you without knowing what happened.

This issue is fixed and the fix is coming on the next update.
