Yeah the pilots in the squad both have their info downloaded separately already..
Try m00t and muut, tours 91-106 and 39-48 respectively. I thought it might be the gap in the two data, but even changing it to e.g. 58-67 and 44-48 and crashes the program..
Maybe the tours of the squad members have to overlap? Now it won't let me make a squad with just muut in it. But it does work if I use an actual HTC squad CO like Fester, on his own as a squad.
