Hi Jeremy,
To follow up on this – I am wondering if the issue with saving is also affecting the files that I need to preload. For instance, for the following experiment (https://farm.pcibex.net/r/MxiUwp/), I just changed the names of the files on my .csv and updated the .zip folder that has the corresponding video files on the server. But, the downloads that are happening are just for the files that were previously unchanged. I haven’t changed the script besides this.
