When the loop is attached to the end of my master control loop sequence, it only runs once. I deleted everything else so there's just a User Variables activity that reads a parameter file at the start, and now it works fine.
I'm currently going through a process of deleting stuff one by one until it works. Any suggestions?
*Update:* I've worked back from the exec_GetFileList stage that reads the file list, deleting chunks or individual stages, and it only starts working again when everything is gone apart from the uv_Set_Global_Parameters at the very start.
This is my job layout:
