In the new Rise of the Terrans campaign released today, the brand new Star System Information window is NOT displaying the resources in a system:
I thought for a moment that it might be due to the new Binary Star System thing at play in this Campaign, but as the first screenshot shows, it's happening in regular star systems as well.
I haven't submitted a ticket or save for this yet (want to play the new campaign ), but one is wanted, I'll submit it later tonight.
Strangely enough, it looks like this is working partially in other star systems. Here is an example of one:
At a guess, I would say that the Campaign is picking up the Thulium resource but not the Durantium in that system. Weird.
