Though "About landmark" is a viewer think, it relies on info given by the 
server.
Having the same issues as with the internal GetRegionByUUID leads me to the 
conclusion that the failure is a server thing.

I made additional test using my OSGrid account, and got the same issues (leads 
me to thing it's not a config issue, but a software issue)

Here is the detailed process:

- Hyperlink to a foreign grid and add a landmark
        -> in some places, the landmark shows as local, but this seems to be a 
foreign-grid config or server version issue (to be confirmed)
        -> I made test with both landmarks showing as local and landmarks 
showing as HG
- Go back to a sim on your grid and display "about landmark". 
        -> at this stage it displays complete information, including 
gatekeeper, description, region name…
        -> if patch is applied, the function osGetInventoryLandmarkParams  
returns relevant information 
        -> typing "show hyperlinks" in sim's console show the temporary linked 
region
- Log off, shut down and restart your sim (restarting robust is not mandatory 
to observe the issue)
- Go back to your sim and  display "about landmark" again
        -> it displays only basic information (same as information available in 
landmark name and landmark desc)
        -> if patch is applied, the function osGetInventoryLandmarkParams  
returns only information not depending of region info, and gatekeeper is 
incorrect
        -> typing "show hyperlinks" in sim's console show the temporary linked 
region has disappeared (as expected)

In both cases, landmark teleport does work, whatever information is available.

As landmark info is a feature depending on info given by the server, the server 
should have a fallback process to request new information if HG region is 
unlinked
