Dear Ana,
Did you leave the Debug window open, and if so, does it report any error message?
Does your script refer to that CSV file in a Template command? If so, does commenting out the Template command make the problem go away, or does it persist regardless as long as the CSV file is in your Resources/chunk_includes folder?
Feel free to let me know (here or at support@pcibex.net) what account/experiment you’re experiencing this issue with, and I’ll take a look
Best,
Jeremy
