Nevermind, it seems there was some bug witht the map itself when it loaded.
I entered the roo and there where no enemies at all and only realised the bug when I reached the cutscene at the last room.
To fix such a problem it seems you need to re-enter the previous map so that enemies can load up again and then eter the last map where hopefully youll get all the enemies spawned normally and the cutscene will work.
In more Detail what I did was restart the game which didn't fix anything, loaded the previous save which didnt work either (in fact when such a bug appears even if you travel to the battle tower there will be no enemies or people around at all, no clchemists no servants no dancer no nothing!) so at this point I used the portal to travel to another map (Orobas Fjords) which had people and things loaded up normally, and then reentered Kali's flying Fortress and then Kali's Headquarters and finnaly, after killing some new enemies that where not there before, killed Kali in her unbugged room.
