Influence starbases
When you construct an influence starbase it increases your influence by a percentage. Does the starbase's influence ring have to be around a planet for that planet's influence to increase or does it just increased influence whereever it is placed? I just realized that I've been thinking it just increases my influence wherever I place it, but maybe it works like the economy starbases that increase the trade amount of the routes that pass through its ring of influence.
Any insight into this would be great. Thanks!
