[18.5 - ground combat] can't target alien in LOS

[Omots]

I have several soldiers with an alien in their line of sight, but could not get any targeting reticle to lock on to the alien. The reticle bounced around erratically with the slightest movement of the cursor. There is a train car between me and the alien. The car is ghosted so that I can see the alien.

I did not overwrite the save (still have it), and went back to it to recreate the problem. Of course, the second time, everything seemed to work OK - although the alien's position behind the car was not the same as when the problem occurred.

Here's a picture of the recreated event.
