[MOD] Few questions without answers

[adan_eslavo]

I play with modded VP, but these are rather overall issues. I have stucked at few problems:
1. I use following codes:

function OnSpawnChangeSelected(eCs)
    local bSpawnDisabled = Players[eCs]:IsMinorCivUnitSpawningDisabled(Game.GetActivePlayer())
    Network.SendMinorNoUnitSpawning(eCs, not bSpawnDisabled)
    InitCsList()
end

and

function OnPledgeProtectionSelected(eCs)
    local bPledgeProtect = Players[Game.GetActivePlayer()]:IsProtectingMinor(eCs)
    Network.SendPledgeMinorProtection(eCs, not bPledgeProtect)
    InitCsList()
end

The problem is that InitCsList triggers before changes to Cs are set in the game (unit spawn option or pledge protect option). I cannot find any events related to those 2 mentioned situations. How can I trigger this function after the change? Maybe there's useful delay? I used simple while loop delay but it didn't work at all.

2. I want to show espionage window on top of current popup (Diplomacy Overview) click using following code:

function OnSpySelected()
Events.SerialEventGameMessagePopup({Type=ButtonPopupTypes.BUTTONPOPUP_ESPIONAGE_OVERVIEW})
    --UIManager:QueuePopup(ContextPtr, PopupPriority.eUtmost)

but it shows underneath current window. If I close Diplo window, then I can see espionage window opened. How to make it show on top? I tried to use UI.QueuePopup, but ContextPtr is tied to main window I click the icon from. I run the same way CityState Popup and it shows correctly.

3. Can someone explain what is the difference between:

SerialEventGameMessagePopup
SerialEventGameMessagePopupShown
SerialEventGameMessagePopupProcessed.CallImmediate

4. What does UI.incTurnTimerSemaphore() and UI.decTurnTimerSemaphore() do?

5. Does AI buy mountain tiles? f.e. when Machu Picchu has Mountain requirement does AI rush somehow for it? I used VP and in my mod many Mountain = 1 and NearbyMountainRequired = 1 cases.

6. Original wonders (Stonehenge, Artemis, Great Wall etc.) have two types of models which show on map: one unfinished during their construction, and second when it is finished. Does anyone know where they are declared /programmed/stored? I would try to add more for new wonders.
