I have a quick question. I'm trying to make a "saddle truss" using a KWRocketry bulkhead piece and girders. I made the part, but when I attach it to my craft and launch, the screen flashes to a frozen shot of deep space with no altimeter or velocity readings. When I return to the space center, I can't select any buildings, and when I exit to the main menu, I can't select any of the options, and have to open Task Manager to quit KSP. Moreover, if I load a subassembly with the welded saddle truss, or any vessel with the saddle truss, the ship loads, though the VAB and SPH behave as if the vehicle isn't even there, waiting for me to place a parent part. When I do place a parent part, I still can't launch, exit, save, or load ships (the buttons react when clicked, but nothing happens). Is this a problem on my end, with the KWRocketry part I'm using (specifically the 3.75m bulkhead), or is this a known bug? Thanks!
