The script is very basic, as it does only one thing. When triggered, if the indexed group has internal records (documents and/or sub-folders), export them to the indexed group’s folder in the filesystem (Finder)*. There really isn’t anything to debug/troubleshoot to get working properly, and I’ve never seen DEVONthink remove any attached script from a group. I also used a more complicated version of this script (included sync and deconsolidate commands) for a very long time on all my databases. I only stopped using it when the sync command was incorporated into DEVONthink. See the pinned topic at the top of this forum here. I have to believe that there is something else creating a problem here, but I’m at a loss as to what to suggest you try.
*From the DEVONthink script dictionary:
deconsolidate v : Move an internal/imported record (and its children) to the enclosing external folder in the filesystem. Creation/Modification dates, Spotlight comments and OpenMeta tags are immediately updated.
deconsolidate
record record : The record to deconsolidate.
