Kuva Lich rescue missions on Corpus tilesets use corpus troops

[Myrvair]

In lich missions, if the mission is by default rescue from Corpus and using corpus tileset, despite lich and its retinue being Grineer, the wardens sometimes are also Corpus and engage in battle with said Grineer troopers if the player approaches. Funnily enough both groups seems to often not notice each other (as observed from afar) till entering 'hostile' state by player's arrival.
