[V19 stable Hotfix - ground combat] graphic errors and through wall shooting

I know that this was an issue in a former version, but I haven't encountered it for some time.

Now I have landed near a massive terror mission ufo instead of going into the city. I have never seen that so far. Also my soldier had dread the first time, which I guess is because of the evil master alien.

However, outside the ufo some Androns were hiding behind cover and shooting at me, but my soldier could not reach them. The ufo was highlighted green when trying to aim them, guns or grenades. If the ufo was not highlighted the aim did trailed away from them and grenades could not be thrown.

Inside the ufo I could see aliens outside, but couldn't aim. They could and shot also. They did hit the hull of the ufo multiple times but some shots got through and a red number hovered somewhere to indicate loss of life. However, the "hit" soldier was not wounded unless it was a direct hit which instantly killed him in one go.

As mentioned this happened before, but the hovering red numbers are new to me.

Also reappearing as I haven't seen it for some time is that there are overlapping graphics.
