Enemies bugged out and disappeared

I went to save a Jericho base from an alien attack. I fought through the whole mission and killed the big bad guy at the end of the city block. He was the huge walker that spaws mind sucker worms. When he dies they sometimes come out. Well, I moved my flamer forward and started roasting the ink blackness.
The game battle cliched out and the enemies never spawned. I kept getting radar trails in two different spots. I evacuated all the civilians and my squad. the game would at least score me a partial for saving all the civilians. It scored me nothing.

It is a good game but needs a good scrub for bugs. Don’t add any more content until you worked through these underlining issues.

You didn’t comment on my other post so I am not sure if you want the save.
