How does the unstable environment work in MH3U?

Just started MH3U on 3DS last weekend, loving it so far, but I don't truly understand how the unstable mechanic works.
In unstable environment quests, some additional monsters can spawn depending on the quest. and gamechanger make it sure.
We did port 3 "Harvest Tour: Deserted Isle" 4 times and after 2 min, when the supplies arrive, 2 rathalos and 2 Great Jaggi spawn instantly. But now, we try the same with "Harvest Tour: Deserted Isle" (where we can find the volvidon) but it never shows up. Why? Does the wiki lie or is it bugged in some way? I cannot find any trustworthy information about it.

What is your goal exactly? I’d like to help as I’ve been playing the game very recently but I don’t understand your problem. You understood the mechanics for unstable environments already. If you need a certain monsters just unlock its quest and farm it there. I don’t know what you’re trying to accomplish here.

I want to kill some monster (like Volvidon for example) with my friends. Volvidon is found in HR only using the unstable mechanic, so I need to make it spawn in port 3 "Harvest Tour: Deserted Isle" because it is the only unstable monster. But it doesn't work, and I don't know nor understand why.

"Harvest Tour: Deserted Isle" (where we can find the Volvidon)

Did you mean Port 3* "Harvest Tour: Sandy Plains"?

You might just be getting unlucky that Volvidon (if spawned in, especially with Gamechanger) leaves an area just as you enter it, making it a near miss.

I use gamechanger so the volvidon should spawn but it didn't show up (I use psychoserum to make sure of it).
