STAAD Advanced Foundations crashing when trying to design a mat. After I have analyze the mat I review the calculations to see what my bearing pressure is and it is usually around 1.17 ksf. I then try to apply the Moment Envelope Generation and when I press Generate Moment Envelope it crashes. Here are the "Problem details":
