If you have this mod, and bob's assembling machines, the bob's assembling machine number 4 takes over, and overrides this one, so its like you never had it at all. This is a pitty, because even when its obvious you won't need bobs assembling machines, his mod also gives you extra tiers of other usefull machines, such as chemical plants, refinings, and some others, so would be wonderful having this mod and also bob's without loosing any of their contents
