Hi Jakob, 
thanks for reaching out! 
It seems that this error might appear if you have a matrix with a determinant of 0. Then finding the inverse of the matrix might produce an error, as we’re trying to divide by 0. 
You can try and check if the input for your extended model. If there’s some mismatch in the number of parameters or the variables values, it might be what’s causing the issue. 
Let us know how you get on!
 
Best,
