Vaal ruins temple misunderstanding

Hi,.

Isn't suppose to save the temple?

I started a vaal temple in act 3 with Alva asking what was this and she accompany my character at the entrance.

I placed all the very nice chambers I had. Hitted RUN temple, went in until the first checkpoint.

I exited thinking Id be able to come back, but it did not save. I lost all the rooms, and have to restart anew.

What happen?

I don't understand

Thanks if someone reads this and know

Ok, so we don't know how but Alva Valai (and we think Zana) can mess with time, so obviously she sent you through a time portal to back before you built that temple and now you have a new one to build.

Also https://www.poe2wiki.net/wiki/Atziri%27s_Temple

the one you were building was probably the lost temple and now its atziri's temple.

Ok,
What about closing the temple?

When I completed the lost temple, I wanted to try the "Close temple" without indications in game.

I saw a couple of rooms disapear (destabilize)


Does it destabilize automatically when I get out of the temple after I completed it? Hitting close seems a bad idea.

Actually I never notice any room destruction before hitting "Close temple"......
