Sounds like your helpers are saving there own 'revision' of the file as they work on it?
If that is the case (and is perfectly fine for archiving purposes), then the helpers need to be told not to use the recent files list.
Always open from the operating system file manager or browse for the file when opening in Archicad.
If they were all simply saving the same file (I assume on a network server) and not with different revisions, then no matter which machine they open it from, it will open the same file - if they have that file in their recent list.
We work like this in the office I am in.
But if they are all saving them as different revisions as they work on it, there is no way for the other uses to automatically have a link to that new file.
I know that is why you want to turn the recent file list off, but the users just have to know not to use it.
I wonder if there is a Registry key (Windows - plist I think on Mac) that can disable the list?
Maybe BIMCloud could be a solution - I am not sure as I don't use it.
But I assume you would still have the same problem if different revisions are being saved.

I am a solo operator at the moment. but spent the last 11 years in a small office (10 licenses) using BIMcloud (basic) on every project. As far as I know no one ever opened the wrong project or version. Dealing with solo projects on DropBox seems primitive by comparison, especially dealing with office libraries. Since I am usually collaborating with at least one other Archicad user I am considering spinning up my own BIMcloud basic or BIMcloud SaaS.
