It looks like I fixed bug from the comments by forsing game to slow mode at the beginning of every player turn. For the time being it works fine on my game.

To do this you need to find file "Zug_FastForwardAI_GP.lua" (in the same folder as the settings file), then inside file replace this text:

function SetQuickAction (playerID, blsFirstTime)
if (Players[playerID] ~= nil and Players[playerID]:IsHuman () == false and blsFirstTime == true) then
ExposedMembers.Zug_FastForwardAI.SetStoredQuick (true, true);
end

end

with this:

function SetQuickAction (playerID, blsFirstTime)
if (Players[playerID] ~= nil and Players[playerID]:IsHuman () == false and blsFirstTime == true) then
ExposedMembers.Zug_FastForwardAI.SetStoredQuick (true, true);
end
if (Players[playerID] ~= nil and Players[playerID]:IsHuman () == true and blsFirstTime == true) then
ExposedMembers.Zug_FastForwardAI.SetStoredQuick (false, false);
end
end

I hope this will be useful for author and players))
