Dear Marije,
I looked up our database, and your project does have a total of 25 submissions, with the most recent being received on 2021-12-22, and the one before that on 2021-11-22
All these submissions represent a total of 62300 rows, so you can download them in a single batch with no worries of exceeding the 100000 line threshold
Submissions are not always ordered chronologically in the results file (something I should fix). Could you double-check whether the December 22 submission appears somewhere before the November 22 when you download your results in batches?
Jeremy
