The program crashed after I ran the following set of codes from p.78 in Ngene 112 manual. Any idea what went wrong?

?This will generate a simultaneous orthogonal design wtih interactions between x2*x3
?This will crash!
Design
;alts = alt1, alt2, alt3
;rows = 8
;orth =sim
;model:
U(alt1) = b01 + b1*x1[0,1] + b2*x2[0,1] +b3*x1*x2 /
U(alt2) = b02 + b1*x1[0,1] + b2*x2[0,1] /
U(alt3) = b1*x1[0,1] + b2*x2[0,1] $

Thank you for bringing this to our attention.
We will investigate why this happens.

Thanks for the spot. This is a bug that has been introduced with version 1.2 (due to some new functionality we added). We will fix this in 1.2.1, which should be out in the next 1-2 months.

In the meantime, if a simultaneous orthogonal design with two way interactions is required, you can install and use Ngene 1.1.2, which can be downloaded with this link: https://www.dropbox.com/s/135nxvgv1hq0j ... p.zip?dl=0
