can't build matter decompressor

Have to ask - I assume you have the Ascension perk? And you're not building another one?

Usually if you select your construction ship, and click the megastructure button, it'll tell you why you can't build it.

I just got one built. I needed a Black Hole with an Outpost claiming the system. I had to disband all of my existing Mining and Research stations in the system. Then it let me build it.

The catches:

- There was no yellow indicator around the Black Hole when it was able to be build upon
- There was no error message earlier as to why I could not build.

Edit: now after finishing construction of the Matter Decompressor, I can rebuild the Mining stations in the system, but not the Research stations. I think it was the presence of the Research Station on around the Black Hole that caused the problem.

JUST CLICK LIKE YOU WOULD BUILD IT ANYWAY

Seems sometimes the build location indicator bugs out and does not show. After fault finding for an hour with no luck I just attempted to build it on my local black hole and it worked.

Good luck captains, I hope you die furiously in your next ironman attempt.

When it comes to matter compressors; I suspect that the location pop up tends to get hidden by the black hole (its shows up behind it).

Well you can build it on literally any black hole within your borders, though there is no indicator like for other megastructures. You also don't need to dismantle any research stations, this requirement was removed in the same patch which let you build habitats on top of stations.

So you select the matter decompressor in the construction ship's megastructure menu, click on the black hole, and you should see the path indicator, proving that the order is correctly processed.

The usual restriction of 1 megastructure per star system at a time still applies. Same like you can only build either a gateway or a habitat, otherwise you get the message "another ship is already performing this order" or something like that.

I've had this issue as well. Right clicking on the black hole and selecting "build megastructure" revealed that the matter decompressor cannot be built in systems with habitable planets.

Right click build on blackhole, Common issue.
