TL;DR
Let the electromagnetic plant craft beacons.What ?
Add beacons to the assortment of items that can be crafted in the electromagnetic plant, alongside power poles, accumulators, etc.Why ?
There are two main reasons I think this should be done:1) Beacons are used in large quantities, and are relatively expensive, so letting the recipe benefit from the added speed and productivity of the electromagnetic plant would be very useful to players.
2) Beacons are obviously very “electromagnetic” in concept and design. They’re also directly part of the module system, which the electromagnetic plant is already linked to. So it would be thematically fitting.
Of course, it was never specifically stated the electromagnetic plant could not craft beacons, this may or may not already be a feature behind the scenes, but I’m suggesting it just in case.
