Craig - the city update process is automatic now. As undersand it, James’ code cycles through any city with active runners in it on a rolling basis so things get checked and updated about ever 1.5-2.5 mos depending on the load.
Nothing special needed for your city to get updated. If the “updated” date on the city page was more than a couple of mos old and you knew there were changes, then it might be worth a check.
Right now Waterford was last updated 5/8 so that was only 2 weeks ago, I’d expect another update by late June, early July based on my experience.
James recently released the city update notifications feature, so you can check that out if you want to be notified.
