Why cant i place any megastructures

[The Shadow Rose]

So this will sound stupid but how do i actually put them down? I played this game for a longgggg time but they switched something somewhere in the placing of megastructures and now i cant place any of them but a gateway anything else it either says my starbase is in the way or if i just click the megastructure it doesnt give me a little highlight of where to place it since im guessing most of them can only be around the star/black hole. So what am i missing -.-

On a side note does having an active gateway mean im bordering another empire who has an active gateway or is that wormholes only.

The megastructures that are built on a star in a system requires you to remove the mining/research station first in most cases.

About gateways: I can't remember if you get the same opinion penalty with gateways, but trade routes use gateways and wormholes so maybe.

With regards of the megastructures as Maghnus said most of them needs the mining/research station removed, and also you can only build/upgrade 1 megastructure at a time to my knowledge.

In regards of gateways I'm 99% sure that it counts as bordering them, at least for influence cost of claims, since the L-gateway works that way (if you own the initial gate system in the L-cluster at least)

select build ship and look in the menue in the lower left corner! there is a build megastructure button, use this instead of right clicking the system you wanna build in. There you have a view that will notify you with a green mark on planets or whatever that you can build the megastructure you selected

I think i might have had a mod that made building certain megastructures impossible. If you're modding just be warned that your problems might be from that.

Example: I couldn't place a dyson sphere after removing whatever was on the central star.

In general, the guidance for placing a megastructure is pretty much ZERO. You click the button and hope that you're in a system that can have that megastructure in it. If it can't then you have to keep looking around. Why the megastructure doesn't just remove the mining station, who the ♥♥♥♥ knows? Why systems that can have the requested megastructure aren't highlighted in the galaxy view, dunno. Why you can't click on the star and say 'build dyson sphere'. Construction ships add almost zero the the gameplay.

Anyway, there are rules many of which are outdated on the internet about where different structures can go. The minerals one needs to go on a black hole, i haven't been able to build the unity one, who knows where the ♥♥♥♥ that goes. Gateways need to be built outside the system center (how are you supposed to know that? Magic.)
