Pinpointed it a bit more. Two times now this red fighter icon appeared with the eBuilding pop up, and it pointed to the same spot on the southpole. I entered the worldbuilder ASAP when I located it and nothing is to be seen there. Also, all cities in the map were in the middle of construction, so it's not some building/unit being finished.
It seems the game crashes down if you're too close to that spot if this pop up appears.
Btw, the colony pods appear fine, the marker shortcut is *real* handy on the spot, the available range marker a must have but I'm not so convinced for the citycross thing. Perhaps since I know the patch will come with something less obtrusive.
I'll dl it again and do as you ask, Belizan
