There seems to be a bug in PRTG Network Monitor 22.214.171.1243 when cloning a map & then changing a sensor object to point to another sensor.
I have an existing map, which I clone. On the new map, I select a graph object (it's a sensor factory live graph) and then click Select Object from the properties window. I browse to a different sensor factory object and click OK.
The field "External link" is updated to reflect the new sensor ID, but the graph shown on the map is still the old object's graph. Nothing I've tried gets it to show the right graph (including rebooting both the remote probe where the device is hosted & the main prtg server).
It's easily reproducible in my setup, let me know if more info is needed. Thanks.
