Dear @dbryce ,
Under some (hopefully rare) circumstances, the .csv files might be missing from the GitLab repository, but I believe they would have been saved to your experiment repository on the Pavlovia server (as opposed to the Pavlovia GitLab server). Consequently, they would be available to you through the [Download results] button on the Pavlovia page for your experiment. Could I ask you to check whether that is indeed the case?
If you could you share the full path of the experiment(s) you ran for your tests, I could also check on my end.
Best wishes,
Alain
