Custom race: can't always build hypermatrix
When I use a custom race (with the respective tech tree, can't think of the name of the race it belongs to) with the tech tree that contains the hypermatrix, I can't always build it. I'm not sure if I'm just missing a precondition but with some games that I start, I can build it right away, and in other games it's not listed as a build option (same custom race), and I can't think of what might cause this. Any idea whether that's a problem/oversight on my part, or a real bug?
Edit: This happens with TA 2.0
