Is it possible to overlap a submerged conveyor belt with an above-ground one?
Nope. I tried once, and learned that, as in the real world, planning is an important aspect of business. Besides the research that should be put in before expecting to operate a successful business, one needs to also plan out a credible floor plan. With proper planning, you can get a plastic case machine output feeding right into a Long Player input, and capitalize on the plastic case while dramatically cutting the cost of producing a Long Player!
