No TDoA map
When I access the TDoA extension on my KiwiSDR, no map of KiwiSDRs are displayed - where the map should be is grey. What might I be doing wrong to cause this? I see some chatter somewhere where my KiwiSDR was used by someone to DF something, so am sure I've cocked something up after finally getting things going again after returning home from KH6.

Open the console window using these key sequences:
Mac: Firefox cmd-alt-K, Chrome cmd-alt-J, Safari cmd-alt-C
Windows: probably ctrl key instead of cmd.
Also, try it using the old deprecated Google maps just to see what happens. Start the TDoA extension from the URL using the "gmap:" parameter (note ":" after gmap), e.g. http://mykiwi:8073/?ext=tdoa,gmap:

Interesting that Google maps works. We really need to see error messages from the console..

There is still a bug where sometimes after a map change some of the map tiles are grey. They will "fill-in" if you drag the map around a little bit. I still don't understand what causes this.
Also, there used to be a problem getting a proper TDoA solution when the map was positioned such that it crossed the 180 degree "anti-meridian" (i.e. to the east of New Zealand and Fiji and the antipode to Greenwich). But it seems to be working in your example so maybe it's not an issue anymore. It was on my infinite list of issues to look at.
Yes, TDoA map working fine after that update sometime back. So far, haven't run into the grey tile or 180 degree longitude problems, so perhaps they are also no more.
That might have been JORN from VK8, but at other times when doing a number of runs eventually I get a few grouping around the VK4 site. Sometimes the bursts look a little different - which previously I thought might help identify which site was being heard - but now nearly 13 years after figuring out we've had supposedly white hat country OTHR in the ham bands, there hasn't been must interest by hams in the source countries to confirm or even complain them.
I previously used to DF OTHR by the hammer & chisel method, taking bearings with directional antennas where possible whilst traveling. Here's an example of when I was able to confirm what we had been hearing on 15m was indeed JORN.
