Zana missions & map device portals shared

Highly doubt this was an intended byproduct of the moving of the portals that was done in this patch to prevent us from losing them on an instance crash. But this is also super easy to replicate;
1. Start a map with Zana on (or find a wild Zana)
2. Activate the Zana mission and enter that map.
3. Exit the Zana map.
4. Exit the map.
5. Congrats you've somehow only entered the map once but consumed 2 portals.
Images below are from the last time this happened. I had found this Zana really close to the start of my map and somehow I burned through half my portals into Forbidden Woods when I only left it after finishing the Zana map to vendor and inventory sort. Notice the portals to Overgrown Ruin are 1 higher then the ones into Forbidden Woods.

This happened to me as well. Same process and everything.

not only zana maps. abyssal depths, vaal areas etc too

Also, if this bug makes you run out of portals on the outer map, then you can't leave the inner zana map

This is probably completely irrelevant to the issue but I'll share anyway just in case it's somehow related...
Before 3.16. if you opened new portals and clicked the first one right after it opened while the other 5 were still opening, once you completed the map and went back to the hideout, the remainder of the portals would have been already opened whereas now when you do the same thing, once you go back to the hideout the portals continue being opened once you arrive there (portal opening sequence is paused the moment the player leaves the hideout instance).

Yep, this is clearly a bug. I had this issue 2 times. I left my main map once yet I lost all portals because of Zana map.
Weird is I died In Zana map once, so I thought I go to hid and drop all loot. I opened 1st portal back and I already had only 2 portals left. So for some reason going to Zana map an dying there ate 3 extra portals on main map.

same issue cant enter friend's zana missions...
