[2.0.19] Vulcanus briefing never appears in Tips and Tricks menu

[Xenonex]

I'm using the current experimental on Steam, 2.0.19

1. What did you do?
I researched the Vulcanus technology, traveled there on a space platform, dropped to the planet, harvested Tungsten & Calcite, built a Foundry and then a Big Mining Drill, and eventually some Tungsten Plates.

2. What happened?
At no point did the "Vulcanus Briefing" entry unlock / appear in the Tip and Tricks menu like it did for the other planets I visited (Gleba & Fulgora). No other potential Vulcanus-related entries have appeared either (I'm not sure whether any exist or not).

3. What did you expect to happen instead?
I expected that at some point during the above series of events the Vulcanus Briefing entry would unlock / appear.

4. Does it happen always, once, or sometimes?
At least for my current save file, this seems to keep happening each time I reload a save before landing on Vulcanus, or reload a save even before researching Vulcanus and then arrive all over again.

Attached are save files (with mods disabled) from just before completing the research to unlock Vulcanus and just before landing on Vulcanus, which at least for me keep repeating this issue when I reload them.

Other users appear to be having a similar issue but for different planets here.
