Yes, economy influence used to be instant after all the commodity deliveries had been completed, even when the signs on the station said it was under deployment. Makes me wonder if FD changed something so the station does have to be completely finished now. I have zero proof of this actually being the case, it might just be that everything is just broken right now.Not operational yet. But has market.
Edit: we built working economies in non-operational stations before. And economy influence was quasi instant before.
