Sometimes, electrons dance differently.
One of the outcomes of this is that a student (or a few) will not get an assignment generated. Students are usually pretty vocal if they don't see something they're told should be there. To resolve such a case..
Have assignment.id or learningmodule.id (ie sys admin: from the instructor assignment view--ex lrm837j, lmod 378597). masq as instructor (sys admin, masq) go to assignment of interest, grab assignment.id or lmod.id in address line (ex end of URL: assignment_1487935 ).
Take this number to the cua drill down page ( https://quest.cns.utexas.edu/institutionadmin/institutions/show?institutioncredential=72276 ) and place in relevant box under 'elements' (assignment.id on left, lmod.id on right), view.
At bottom of next page, click 'CUA, Tex, and PDF'. on next page at bottom of page click 'generate missing cuas' blue button at the bottom.(this is a batch job, usally pretty fast though)
to check: look for 'generation completed' in above student assignment staus box for that eid, AND/OR masq as that eid person (student) , verify when the assignment shows up for them.
