Dear all,
I need your help to make this work.
I'm using version 1.3.0+hg2018-02-10 (r:03d13e730d9a) on a Debian 9.5 "stretch" (4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux).
My MWE compiles without errors, but no questions are printed on the question pages and no answers expected on the answer sheet.
To get some output, uncomment the lines 143 and 150:

    % \insertgroup{draw-manuallyEntered}      % line 143
    % \insertgroup{describe-manuallyEntered}  % line 150

I also tried TeX's native \loop ... \repeat approach, with the same results: no errors, no questions, no answers.

1. So, what am I doing wrongly here?
2. And why don't I get an error if the groups to be inserted really are empty?

Any help will be appreciated.
Thanks,
Darki

PS Of course I am aware of the crude solution: to create all the \element{...}:s manually (and edit all the instances when a change is needed later!) and I will do that if my deadline to print the test is reached with the loop-based solution still failing.
