I just ran into a WTF moment, you could say.
I was playing TEC on the custom map Milky Way. Now there are several wormholes in there and after finishing the Wormhole Navigation research, I tried to tell my ships to navigate that wormhole in my starting system...futilely so, I might add. They just stopped right in front of the center and even evaded it when I told them to go to the other side of the well.
I have the latest version of Sins Plus for Entrenchment 1.02 installed,
Maybe that caused my problems? Any help would be greatly appreciated.
