Last mission is crashing everytime, cannot finish the game.

[Kamurotetsu]

I can't complete this game, it's crashing in the last mission "Temple Ship Assault." Whenever I enter the first door and reveal the two Sectoids and Commander, then finish my turn, it crashes. I've tried getting everyone in there and not attack, it crashes, I've killed the three enemies, it still crashes. 

 

Anyone who has the plat or completed this mission, what did you do?

 

Edit: Figured it out, some enemies are teleporting in. You need to wait outside the first door, throw a grenade/use a Heavy rocket or run in and back out to reveal the enemies, then wait for the teleport. Make sure your Assaults have Lightning Reflex because you're at a disadvantage as they will use Overwatch. TL:DR, just play the PS3 version, not worth it.
