Pavlovia no longer downloads experiment results

URL of experiment:

Description of the problem: I have been running an experiment since October. I had no problem downloading the results until a couple of days ago. The file that I download now only includes the results from the first couple of sessions, the more recent results are gone. I have not done any changes experiment documents to since their initial upload to Pavlovia. Any idea why this might have happened and how I can fix it?
