I have been experimenting with both advent factions since the release of Beta 2 and I have noticed that Crystal resource lags behind metal no matter what I do. I even went so far as to try as Advent loyalist with no metal upgrades and max crystal upgrades. Even so crystal production lagged far behind.
Has anyone else noticed this? If it was just one match I might put in down to poor access to crystal asteroids, but in three matches? And even after several hours and many acquired ice planets, crystal just does not gain at any significant rate.
