Uncaught TypeError: Cannot read property 'userName' of undefined wme_uroverview.3.11.1.user.js:1893
I'm still trying to pin down the specific sequence of events that appear to cause this to happen (which then breaks the other functionality of the script - e.g. no more UR popups, etc), but it seems to happen after I have zoomed in and out (perhaps while some of the layers are still loading?).
EDIT: So after more investigation it appears this can happen either when zooming in/out or just moving the map around, and occurs when the userID of an AM of the current visible area is no longer present in the Waze.model.users.objects Object (which I guess only contains user Objects that are relevant to what is currently displayed in the WME window?).
So, again this is mostly conjecture, does that mean if an AM for the area currently visible is not associated with any of the visible segments, it's not possible to resolve the userID to username & rank?
Twister-UK - I'm sure you've already worked this all out for yourself, but I was intrigued about what was happening so did some debugging to satisfy my curiosity...
