[V18 stable - Xenonauts base attack] alien contact at beginning and targetting issue

[thixotrop]

In a sudden base attack - ufos appeared on top of my base- the aliens were already visible at deployment phase. I don't know if that should happen. (Nevertheless this was quite nice because all the grenades had a lot to eat through in that narrow room full of aliens.)

This was the only room with aliens:

I have saved the game before I deployed my soldiers. I tried to throw grenades but the first soldier completely failed and dropped the grenade: Two of my soldiers wounded. Reaction fire of the aliens killed three soldiers. Damn!

So I reloaded the game, but then deployment was not possible anymore. Similar as mentioned before (here).

With the reloaded game I moved my soldiers a bit before throwing grenades and now it worked. Nailed a lot of them. One or two escaped to the radar room. Nevertheless they could be killed as the shots found them, although a different alien was targetted. There seemed to be an obstacle in that smoke but the hit animation was in the radar room, this is visible here:

Both escaped aliens seemed to be on one common tile, didn't move and were killed.

As the smoke was gone no obstacle could be seen:

When I tried to target the "obstacle" the crosshair jumped to the already dead aliens in the radar room:

I have saved during the battle, but the reloaded game did not have this effect anymore.
